Conceptual Design of Fuzzy Rule Based Context Aware Meeting Room System
Due to the exponential growth of wireless network based miniaturized device and
sensors, the dream of context aware ubiquitous computing world is becoming realistic. In this
ubiquitous world of context aware applications the users can get the information and share the
information elsewhere instantaneously. Context aware meeting room is one of the interesting context
aware systems where in the meeting of a given set of users will be organized as per the situation of
users. In this paper we present the conceptual design and development of service recommendation
system for prototypical context aware meeting room using Fuzzy Rules .The proposed
recommendation system for context aware meeting room recommends the services by considering
the users contextual parameters like role, priority and environmental conditions. The fuzzy rule is
constructed using history database and knowledge base of the meeting.

Modular Construction consists of one or more structure units fabricated in a
manufacturing plant away from the jobsite. In the building industry, prefabricated
modules are normally completed with trim work, electrical, mechanical and plumbing
installed. Previous studies have proved that Modular Construction provided many
advantages to the built environment, including the reduction of need for workforce,
the reduction of onsite Green House Gas (GHG) emissions, and the improvement of
construction schedule and product quality; however the extensive demand of pre-
project planning and coordination among members of cross-interdisciplinary
professionals have significantly impeded the application of this technique. With the
recent development of Building Information Modeling (BIM), these challenges could
be overcome through the BIM platform. Through case studies the benefits and
challenges of implementing BIM in modular construction are clearly identified.
Keywords: Building Information Modeling, Coordination, Prefabrication,

Introduction
Modular construction refers to factory-built building units completely assembled or
fabricated in a manufacturing plant away from the jobsite, then transported and
assembled on site (Pasquire, 2002). Modular building normally consists of multiple
rooms with three-dimensional units, which are constructed and pre-assembled
complete with trim work, mechanical, electrical and plumbing components installed
(O’Brien, 2000). A large portion of construction research conducted in the United
States and globally discusses that the use of modular construction provides many
significant advantages, including: 1) the reduction of overall project schedules, 2) the
improvement of product quality, 3) increased ons.

To date, few construction methods have helped the project managers make a decision on the near-optimum distributions of men, material, Space and tools according to their job objectives and job limitations. This thesis presents an intelligent scheduling system (ISS) that can assist the project managers to find the near-optimum agenda plan according to their job objectives and job limitations. Intelligent scheduling system (ISS) uses model techniques to share out resources and allocate dissimilar levels of priorities to different tricks in each model cycle to find the near-optimum solution. ISS considers and combines most of the important construction factors (agenda of task, expenses, manpower, breathing space, utensils and material) at the same time in a incorporated environment, which makes the resulting agenda that will be nearer to optimum. Moreover, ISS allows for what-if analysis of probable scenarios, and schedule adjustments based on unexpected conditions (modified orders, delayed material delivery, etc.). As a final point, two model applications and one real-world construction job are utilized to illustrate and evaluate the success of ISS with two commonly used software packages, Primavera Project Planner and Microsoft Project.

A Conceptual Model For HCI Design Cases
The document proposes a conceptual model for representing design cases in case-based reasoning (CBR) systems to support human-computer interaction (HCI) design. It reviews the HCI problem and solution spaces and identifies key elements like context of use, user, domain, interaction, interface, and system. The conceptual model defines the structure of an HCI design case, including a problem description, solution description, evaluation, and descriptors. It was evaluated qualitatively by having participants index and retrieve cases during a design activity based on characteristics in the model. The results indicate the model has potential to help designers manage a large set of past HCI design cases in CBR systems by considering a wide view of the HCI design problem and

Backhaul Options for Public Safety
Public safety is undergoing a revolution in situation awareness due to the inclusion of multimedia. Unfortunately, many public safety communication networks were not designed or envisioned to support multimedia and the wealth of other data intensive applications. The increasing use of data and multimedia applications to enhance first responder situation awareness requires that the backhaul network must be capable of supporting this demand. This paper will explore several options available for backhauling large amounts of data in real time
A Survey of Building Robust Business Models in Pervasive Computing
Pervasive computing is one of the most challenging and difficult computing domains nowadays. It includes many architectural challenges like context awareness, adaptability, mobility, availability, and scalability. There are currently few approaches which provide methodologies to build suitable architectural models that are more suited to the nature of the pervasive domain. This area still needs a lot of enhancements in order to let the software business analyst (BA) cognitively handle pervasive applications by using suitable tasks and tools. Accordingly, any proposed research topic that would attempt to define a development methodology can greatly help BAs in modeling pervasive applications with high efficiency. In this survey paper we address some of the most significant and current software engineering practices that are proving to be most effective in building pervasive systems.

This document discusses the need for standardized work breakdown structures (WBS) across project management tools and teams. It presents that without a common classification system, projects lack monitoring, scope management, prioritization, and the ability for stakeholders to exchange information. The document then examines the evolution of using multiple WBS, provides a case study analyzing the need for at least 3 WBS for effective project information management, and outlines considerations for defining rules for WBS use and linking deliverables to WBS for project handover. In conclusion, it emphasizes that complexity in projects requires project managers to have a strong professional background to effectively classify data and integrate information using WBS across systems.
Tracking Project WBS
This document discusses the need for standardized work breakdown structures (WBS) across project management tools and teams. It argues that without a common classification system, projects lack the ability to effectively monitor scope, prioritize tasks, and make decisions. The document then presents a case study demonstrating that effective project management requires at least 3 WBS: scope of work (SOW), operational, and nature code. Rules for using the WBS in management are also defined. Finally, it is concluded that properly defining tagging rules and WBS from the start and implementing them in tools is essential for integrating information and successfully delivering projects.

This document reviews past studies examining the practicability of using Building Information Modeling (BIM) to improve the fourth and fifth dimensions (time and cost) of construction projects. It finds that BIM implementation has the potential to significantly reduce project completion time and costs by simplifying project phases and enabling improved coordination, information sharing, and automation of tasks like quantity take-offs. However, challenges to cost estimators adopting BIM include the learning curve, quality of BIM models, lack of standards and software incompatibility. Case studies show that using BIM software like Autodesk Revit can generate detailed project data and facilitate automatic tracking of element properties and quantities throughout the project lifecycle.

1) Context awareness is important for building management as it allows systems to assist occupants by automatically optimizing conditions like HVAC, lighting, and security based on contextual data.
2) Realizing full context awareness requires enhanced data sources, availability, and context models to integrate information from various building systems and sensors.
3) The project aims to enable context awareness in buildings by using wireless sensor networks to monitor contextual data and support integrated building management and automation.
ESTIMATING THE EFFORT OF MOBILE APPLICATION DEVELOPMENT
The rise of the use of mobile technologies in the world, such as smartphones and tablets,
connected to mobile networks is changing old habits and creating new ways for the society to
access information and interact with computer systems. Thus, traditional information systems
are undergoing a process of adaptation to this new computing context. However, it is important
to note that the characteristics of this new context are different. There are new features and,
thereafter, new possibilities, as well as restrictions that did not exist before. Finally, the systems
developed for this environment have different requirements and characteristics than the
traditional information systems. For this reason, there is the need to reassess the current
knowledge about the processes of planning and building for the development of systems in this
new environment. One area in particular that demands such adaptation is software estimation.
The estimation processes, in general, are based on characteristics of the systems, trying to
quantify the complexity of implementing them. Hence, the main objective of this paper is to
present a proposal for an estimation model for mobile applications, as well as discuss the
applicability of traditional estimation models for the purpose of developing systems in the
context of mobile computing. Hence, the main objective of this paper is to present an effort
estimation model for mobile applications.
Assistant robot through deep learning
This article presents a work oriented to assistive robotics, where a scenario is established for a robot to reach a tool in the hand of a user when they have verbally requested it by his name. For this, three convolutional neural networks are trained, one for recognition of a group of tools, which obtained an accuracy of 98% identifying the tools established for the application, that are scalpel, screwdriver and scissors; one for speech recognition, trained with the names of the tools in Spanish language, where its validation accuracy reaches a 97.5% in the recognition of the words; and another for recognition of the user's hand, taking in consideration the classification of 2 gestures: Open and Closed hand, where a 96.25% accuracy was achieved. With those networks, tests in real-time are performed, presenting results in the delivery of each tool with a 100% of accuracy, i.e. the robot was able to identify correctly what the user requested, recognize correctly each tool and deliver the one need when the user opened their hand, taking an average time of 45 seconds in the execution of the application.

Solution
Use of drones makes the job of law enforcement easier as it enables access to real time
surveillance. Drones helps the police force conduct aeriel surveilance and the video can be
viewed real time or at a later point in time. This is a very useful tool during the investigative
process. Drones can be equipped with thermal cameras so as to keep an eye on anti-social

Backhaul Options for Public Safety
Public safety is undergoing a revolution in situation awareness due to the inclusion of multimedia. Unfortunately, many public safety communication networks were not designed or envisioned to support multimedia and the wealth of other data intensive applications. The increasing use of data and multimedia applications to enhance first responder situation awareness requires that the backhaul network must be capable of supporting this demand. This paper will explore several options available for backhauling large amounts of data in real time
A Survey of Building Robust Business Models in Pervasive Computing
Pervasive computing is one of the most challenging and difficult computing domains nowadays. It includes many architectural challenges like context awareness, adaptability, mobility, availability, and scalability. There are currently few approaches which provide methodologies to build suitable architectural models that are more suited to the nature of the pervasive domain. This area still needs a lot of enhancements in order to let the software business analyst (BA) cognitively handle pervasive applications by using suitable tasks and tools. Accordingly, any proposed research topic that would attempt to define a development methodology can greatly help BAs in modeling pervasive applications with high efficiency. In this survey paper we address some of the most significant and current software engineering practices that are proving to be most effective in building pervasive systems.

TECHNIP
This document discusses the need for standardized work breakdown structures (WBS) across project management tools and teams. It presents that without a common classification system, projects lack monitoring, scope management, prioritization, and the ability for stakeholders to exchange information. The document then examines the evolution of using multiple WBS, provides a case study analyzing the need for at least 3 WBS for effective project information management, and outlines considerations for defining rules for WBS use and linking deliverables to WBS for project handover. In conclusion, it emphasizes that complexity in projects requires project managers to have a strong professional background to effectively classify data and integrate information using WBS across systems.
Tracking Project WBS
This document discusses the need for standardized work breakdown structures (WBS) across project management tools and teams. It argues that without a common classification system, projects lack the ability to effectively monitor scope, prioritize tasks, and make decisions. The document then presents a case study demonstrating that effective project management requires at least 3 WBS: scope of work (SOW), operational, and nature code. Rules for using the WBS in management are also defined. Finally, it is concluded that properly defining tagging rules and WBS from the start and implementing them in tools is essential for integrating information and successfully delivering projects.

This document reviews past studies examining the practicability of using Building Information Modeling (BIM) to improve the fourth and fifth dimensions (time and cost) of construction projects. It finds that BIM implementation has the potential to significantly reduce project completion time and costs by simplifying project phases and enabling improved coordination, information sharing, and automation of tasks like quantity take-offs. However, challenges to cost estimators adopting BIM include the learning curve, quality of BIM models, lack of standards and software incompatibility. Case studies show that using BIM software like Autodesk Revit can generate detailed project data and facilitate automatic tracking of element properties and quantities throughout the project lifecycle.

ESTIMATING THE EFFORT OF MOBILE APPLICATION DEVELOPMENT
The rise of the use of mobile technologies in the world, such as smartphones and tablets,
connected to mobile networks is changing old habits and creating new ways for the society to
access information and interact with computer systems. Thus, traditional information systems
are undergoing a process of adaptation to this new computing context. However, it is important
to note that the characteristics of this new context are different. There are new features and,
thereafter, new possibilities, as well as restrictions that did not exist before. Finally, the systems
developed for this environment have different requirements and characteristics than the
traditional information systems. For this reason, there is the need to reassess the current
knowledge about the processes of planning and building for the development of systems in this
new environment. One area in particular that demands such adaptation is software estimation.
The estimation processes, in general, are based on characteristics of the systems, trying to
quantify the complexity of implementing them. Hence, the main objective of this paper is to
present a proposal for an estimation model for mobile applications, as well as discuss the
applicability of traditional estimation models for the purpose of developing systems in the
context of mobile computing. Hence, the main objective of this paper is to present an effort
estimation model for mobile applications.
Assistant robot through deep learning
This article presents a work oriented to assistive robotics, where a scenario is established for a robot to reach a tool in the hand of a user when they have verbally requested it by his name. For this, three convolutional neural networks are trained, one for recognition of a group of tools, which obtained an accuracy of 98% identifying the tools established for the application, that are scalpel, screwdriver and scissors; one for speech recognition, trained with the names of the tools in Spanish language, where its validation accuracy reaches a 97.5% in the recognition of the words; and another for recognition of the user's hand, taking in consideration the classification of 2 gestures: Open and Closed hand, where a 96.25% accuracy was achieved. With those networks, tests in real-time are performed, presenting results in the delivery of each tool with a 100% of accuracy, i.e. the robot was able to identify correctly what the user requested, recognize correctly each tool and deliver the one need when the user opened their hand, taking an average time of 45 seconds in the execution of the application.

Explain why multiple processes cannot share data easily?
Solution
threads share C.P.U. and just one thread active (running) at a time.
threads among a processes, threads among a processes execute consecutive.
thread will produce youngsters.
if one thread is blocked, another thread will run
hreads don\'t seem to be freelance of 1 another.
all threads will access each address within the task .
thread square measure style to help one alternative. Note that processes would possibly or may
not assist each other as a result of processes could originate from completely different users
A method with multiple threads build a good server for instance printer server.
Because threads will share common information, they are doing not have to be compelled to use
interprocess communication.
Because of the terribly nature, threads will cash in of multiprocessors.
They solely want a stack and storage for registers thus, threads square measure low-cost to form.
Threads use little resources of associate degree software system during which they\'re operating.
That is, threads don\'t want new address house, international information, program code or
software system resources.
Context change square measure quick once operating with threads. the rationale is that we tend
to solely ought to save and/or restore computer, SP and registers
User-level threads doesn\'t need modification to operative systems.
Simple Representation:
every thread is depicted just by a computer, registers, stack and atiny low management block, all
hold on within the user method address house.
Simple Management:
This merely implies that making a thread, change between threads and synchronization between
threads will all be shunned intervention of the kernel.
Fast and Efficient: Thread change isn\'t way more overpriced than a procedure decision.
There is a scarcity of coordination between threads and software system kernel. Therefore,
method as whole gets just one occasion slice irrespect of whether or not method has one thread
or a thousand threads among. it\'s up to every thread to relinquish management to alternative
threads.
User-level threads needs non-blocking systems decision i.e., a multithreaded kernel. Otherwise,
entire method can blocked within the kernel, albeit there square measure runable threads left
within the processes. for instance, if one thread causes a page fault, the method blocks..

create a narrative budget blueprint for a local unit of government. .pdf
create a narrative budget blueprint for a local unit of government. Put yourself in the shoes of an
administrator in a newly formed municipality that has never developed a municipal budget
before. How would you complete the task? Where would you start? What process would you
follow? Who would be involved? What concerns do you have, how do you resolve them? How
do you budget for capital items and link them to the operational budget, etc.? Be as detailed as
possible to display a comprehensive understanding of the course material.
Solution
Municipal Budget :
A municipality is a general-purpose administrative subdivision. It is an urban area usally a city or
town .
Generally Municipalities create Budget on Annual basis. Budget consists of anticipation of
Expected Revenue and Estimated Expenditure.
Generally we start from
a) Revenue :
i) Revenue may be Grants received from Central Government for specific purpouse or general
purpouse.
ii) any local taxes collected from individuals etc will become revenue .
b) Expenditure :
As it is newly formed local unit it can take the basis of any muncipality which is already existing
so that it can cover all administrative expenses like electricity, water, Telephone charges etc.
Sometimes expenditure may be Planned or Unplanned . Therefore amount should be kept aside
as Contingency for UNplanned portion.
Proper authorisation should be there for each and every expenditure.
Expenditure may be for salaries, maintenance of road ways, public parks ,libraries or to provide
Safety services for public, funds for Schools etc
While preparing Budget there might be conflict of ideas.It can be overcomed by meeting the
concerned head of the department.
For Capital budgets Proper Approval, Sanction details Should be verified.
Every member in the unit should be aware of Guidelines respective to there Department.
Through which errors can be avoided.As requisition and payment process done from the unit ,
there should be proper segregation between CApital and revenue expenditure.This can be done if
there are seprate Rules and guidelines for capital and revenue expenditure.
So, in Budget major Focus will be on Revenue and Expenditure..

2.How important is it to involve physicians in financial improvement efforts? What is the best
strategy for physician engagement?
Solution
Physicians are the key player in healthcare system. They have expert knowledge, skills , abilities,
experience, opinions etc. to suggest for formulating the policies related to healthcare
improvements practices. They actually know what is equitable, suitable, right , fair, transparent
and realistic pricing startegies for patients care as well as their payment part in the health care
system.
To engage the physician in healthcare system, the following efforts must be developed and
implemented by the hospital management and healthcare administrators,
1) They should have to report on daily basis to some central authorities related to their day to day
contribution.
2) Their payment and compensation should be kept best among the industry so that they do not
involve themselves in private practices.
3) They should be given some startegic role to analyze the best practices prevalent in the health
care industry.
4) Some training and development activities for future doctors and staffs must be organized by
the hospital so that these physicians can contribute their learning and experience.
5) They should be asked to write some blogs on social platforms so that more people can be
attracted for health care reforms and services offered by the hospital.
6) They should be given some flexibility to choose their plan for making and earning money by
being the part of the helath care system.

Write one page essay to explain how you relate signals and systems t.pdf
Write one page essay to explain how you relate signals and systems theory with current
technology advancement.
Support your argument by providing a case study and identify signals and systems theory plays a
major role on mentioned application.
Please post the website or database you found information. Thank you!
Solution
A signal as referred to in communication systems, signal processing, and electrical engineering is
a function that \"conveys information about the behavior or attributes of some phenomenon. In
the physical world, any quantity exhibiting variation in time or variation in space (such as an
image) is potentially a signal that might provide information on the status of a physical system,
or convey a message between observers, among other possibilities. The IEEE Transactions on
Signal Processing states that the term \"signal\" includes audio, video, speech, image,
communication, geophysical, sonar, radar, medical and musical signals.
Typically, signals are provided by a sensor, and often the original form of a signal is converted to
another form of energy using a transducer. For example, a microphone converts an acoustic
signal to a voltage waveform, and a speaker does the reverse.
The formal study of the information content of signals is the field of information theory. The
information in a signal is usually accompanied by noise. The term noise usually means an
undesirable random disturbance, but is often extended to include unwanted signals conflicting
with the desired signal (such as crosstalk). The prevention of noise is covered in part under the
heading of signal integrity. The separation of desired signals from a background is the field of
signal recovery, one branch of which is estimation theory, a probabilistic approach to
suppressing random disturbances.
Engineering disciplines such as electrical engineering have led the way in the design, study, and
implementation of systems involving transmission, storage, and manipulation of information. In
the latter half of the 20th century, electrical engineering itself separated into several disciplines,
specialising in the design and analysis of systems that manipulate physical signals; electronic
engineering and computer engineering as examples; while design engineering developed to deal
with functional design of man–machine interfaces.
Definitions specific to sub-fields are common. For example, in information theory, a signal is a
codified message, that is, the sequence of states in a communication channel that encodes a
message.
In the context of signal processing, arbitrary binary data streams are not considered as signals,
but only analog and digital signals that are representations of analog physical quantities.
In a communication system, a transmitter encodes a message to a signal, which is carried to a
receiver by the communications channel. For example, the words \"Mary had a little lamb\"
might be the message spoken into a telephone. The telephone transmitter converts th.
Why do IDPs & IDRs lack structure Lack a ligand or partner Denatu.pdf
Why do IDPs & IDRs lack structure? Lack a ligand or partner? Denatured during isolation?
Folding requires conditions found inside cells? Lack of folding encoded by amino acid
sequence?
Solution
IDPs (Intrinsically disordered protein) and IDRs (Intrinsically disordered regions) lack structure
due to lack of folding encoded by amino acid seuence. In general, IDPs are characterized by a
low content of bulky hydrophobic amino acids and a high proportion of polar and charged amino
acids, usually referred to as low hydrophobicity. This property leads to good interactions with
water. Furthermore, high net charges promote disorder because of electrostatic repulsion
resulting from equally charged residues. Thus disordered sequences cannot sufficiently bury a
hydrophobic core to fold into stable globular proteins. Some proteins are fully disordered while
some are partial. Partial disordered proteins have some disordered regions (IDRs). Hence, IDPs
and IDRs have no fix structure and cover a spectrum of states from fully unstructured to partially
structured and include random coils, (pre-)molten globules, and large multi-domain proteins
connected by flexible linkers..

Why is methyl salicylate not appreciably soluble in waterSoluti.pdf
Why is methyl salicylate not appreciably soluble in water?
Solution
Methyl salicylate is not soluble in water due to the presence of benzene ring which is
hydrophobic in nature leading to dispersion forces between the ester molecules. Secondly, the
presence of OH group gives rise to hydrogen bonding with the water molecules. This hydrogen
bonding is weak in nature since the dispersion forces between the two benzene rings are more
leading to decreased solubility of methyl salicylate in water..
Who are stakeholders Define who they are and then please share what.pdf
Who are stakeholders? Define who they are and then please share what particular interest each of
these stakeholders have in the information shared on the income statement, retained earnings
statement, balance sheet and statement of cash flows. How do we analyze if a company is
healthy or not?
Solution
Stakeholders are those persons or group of persons who have a interest in the company. The
Interest that they have may be financial or non financial, such as an employee has a financial
interest but customers have non-financial interest. Stakeholders are concerned about the working
of a company. Stakeholders are of two types
Various Types of Stakeholders are as follows:-
Different stakeholders have different interests in the company. Various Stakeholders and their
Interests are given below.
1.Customers. Customers have a stake in the goods of the company. Customers need to know that
company is making progress; it increases their confidence in using company’s products. All a
Customer need is Good a quality product with future care. A customer can understand from
Income statements of a company that whether companies do any research expenses to make their
product better for consumption.
2. Employees. Employees wants to see what company pays to them as a compensation for their
hard work. Companies Value added statements show the percentage of revenue distributed to
employees of company. Employees are also concerned about their job security. A profit making
company is suppose to give a satisfaction to employee that he has a good future in company.
3.Government. Government Collects takes which can be ascertained by reviewing Income
statement. Moreover companies help government by providing employment to millions of
people. Government has interest in knowing that companies prepare their financial statements
truthfully and frauds like Enron are not done.
4. Stock Holders. Stock Holders are basically owners of a company, They take major decisions
in working of a company. Results shown by income statements, Balance sheets and cash Flow
Statements help them take future decisions with precision.
5. Society. Society is also concerned about the working of business organizations. They have a
stake in Corporate Social Responsibility policies of a company. Whether company is taking
necessary steps to minimize pollution of water, air, or total environment as a whole. The
employment rate is another example of society’s stake in businesses.
6. Suppliers. Suppliers are Concerned about that cash position of company. The Current ratio of
Company. They supply Inventory so they need to know whether company is able to pay their
dues in time. Cash Flow statements show a supplier the position of cash of a company.
7. Creditors. Creditors are concerned about the payment of their dues.
8. Lenders. Lenders such as Bond Holders or Preference stock holders are concerned about the
efficient of use of their money and the return on their money. No one wants to lend his money to

What is UWIN and what does it doSolutionUWin is a software .pdf
What is U/WIN and what does it do?
Solution
U/Win is a software package. It is used to run Unix applications in windows.
For eample if u have some programs which were written for the UNIX environment, you can use
U/WIN to run those programs in windows systems by making few or no changes.
U/WIN contains libraries that emulate UNIX environment by implementing the UNIX API.
Most of the Unix API is implemented by the POSIX.DLL dynamically loaded library (DLL).
Programs linked with POSIX.DLL run under the Win32 subsystem instead of the POSIX
subsystem.
so programs can freely intermix Unix and Win32 library calls..

The Food Stamp Program is Americas first line of defense against hu.pdf
The Food Stamp Program is America\'s first line of defense against hunger for millions of
families. Over half of all participants, am children, one out of six is a low-income older adult.
The function, f(x), models the number of people, in millions, receiving food stamps x years after
1990. Use the graph of f(x) given above the answers to the following questions. How many
million people received food stamps in the year 2004? In which year(s) did 22 million people
receive food stamps?
Solution
a) 10 million
draw a vertical line at x=14 (because 2004 = 1990+14 and see where it intersects with the curve)
b)
year 1992 , 2000
draw a horizontal line at y=22 and see where it intersects with the curve
you would see, it intersects at x = 2 , 10
therefore, 1990 +2 , 1990+10
1992 , 2000.

1)Using the architecture of a house or building as a metaphor, draw .pdf
- 1. 1)Using the architecture of a house or building as a metaphor, draw comparisons with software architecture. How are the disciplines of classical architecture and the software architecture similar? How do they differ? 2) Present two or three examples of applications for each of the architectural styles noted in Section 13.3.1 (A Brief Taxonomy of Architectural Styles) 3) The department of public works for a large city has decide to develop a Web-based pothole tracking and repair system (PHTRS). A description follows: “Citizens can log onto a website and report the location and severity of potholes. As potholes are reported they are logged within a “public works department repair system” and are assigned an identifying number, stored by street address, size (on a scale of 1 to 10), location (middle, curb, etc.), district (determined from street address), and repair priority (determined from the size of the pothole). Work order data are associated with each pothole and includes pothole location and size, repair crew identifying number, number of people on crew, equipment assigned, hours applied to repair, hole status (work in progress, repaired, temporary repair, not repaired), amount of filler material used and cost of repair (computed from hours applied, number of people, material and equipment used). Finally, a damage file is created to hold information about reported damage due to the pothole and includes citizen’s name, address, phone number, type of damage, dollar amount of damage. PHTRS is an on-line system. All queries are to be made interactively.” Use the design approach described in chapter 13 (Archiectural design) to develop a software architecture for the PHTRS. Solution Question 01: Stage in house development Stages in SDLC 1.Design an idea from the architects 1.Think and define the scope or boundary of the concepts 2.Create a plan for the house 2.Develop the project development plan and plan for acquiring resources required for development 3.Contractors Consultation or hiring 3.Create a functional requirement documents 4.Collecting house construction materials while others are engineering 4.Environments set up 5.Get your permits 5.Testing training and transition 6.Rent your house with members 6.Application maintainence Question 02:
