This document proposes a new technique for retrieving hidden information from an image using mobile communications. The sender embeds data into an image using histogram modification and sends it to the receiver. The receiver must enter the sender's mobile number to retrieve a password, which is then used to manually extract the hidden data from the image.

Evaluation of titanium in hydrochloric acid solutions containing corrosion in...IOSR Journals
This document evaluates the corrosion of titanium in hydrochloric acid solutions containing various corrosion inhibitors. Laboratory tests were conducted on titanium coupons immersed in 10% hydrochloric acid at 50°C and 70°C with additions of phenylamine, thiocarbamide, β-naphthol, and a mixture of thiocarbamide and β-naphthol. The results showed that thiocarbamide provided the best corrosion protection, reducing the corrosion rate by 50-80% depending on concentration and temperature. Higher temperatures and concentrations increased corrosion, showing the need for effective corrosion inhibitors when using hydrochloric acid in oil and gas operations.
This document describes a hybrid system using fuzzy logic and support vector machines (SVM) to detect and identify liver disorders in patients. The system first uses fuzzy logic to classify patients' responses to questions as indicating a high, average, or low likelihood of having a liver disorder. Responses are assigned numeric values and summed to determine if the total exceeds a threshold. Patients exceeding the threshold are then analyzed by an SVM trained on data from patients with hepatitis or cirrhosis. The SVM identifies the specific liver disorder present, either hepatitis or cirrhosis. The system was able to accurately perform this binary classification of liver disorders based on a dataset of blood attribute values from patients.

The Comparison of Statistical Quality Control Results on Reinforced Concrete ...ijtsrd
Yangon, the former capital city of Myanmar, gradually increases high rise buildings. But, Myanmar, our country, is one of the countries which still weakened at the quality management system of construction projects. Few construction companies in Myanmar hold the certificates of ISO standards and also there are few people who understand that how much quality is very important for the construction industry. Actually, quality is very important for all stages of construction projects to save time and money of the whole projects. In this situation, two construction projects in Myanmar which are constructed under different construction companies have been chosen to apply the statistical quality control methods to know which areas are needed to emphasis to get the better quality performances of construction projects in Myanmar. This finding can be useful to solve some quality problems of construction projects and by using these statistical quality control methods, quality weak points can be analyzed and reduced to get the better quality performances of the construction project.

This document analyzes the performance of various modulation schemes for achieving energy efficient communication over fading channels in wireless sensor networks. It finds that for long transmission distances, low-order modulations like BPSK are optimal due to their lower SNR requirements. However, as transmission distance decreases, higher-order modulations like 16-QAM and 64-QAM become more optimal since they can transmit more bits per symbol, outweighing their higher SNR needs. Simulations show lifetime extensions up to 550% are possible in short-range networks by using higher-order modulations instead of just BPSK. The optimal modulation depends on transmission distance and balancing the energy used by electronic components versus power amplifiers.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Abstract: Supervision of a project requires a consistent, organized approach to each phase of construction,
and checking the work performed against drawings, specifications, and conditions with contractors and
suppliers. Quality control in construction typically involves insuring compliance with minimum standards of
material and workmanship in order to insure the performance of the facility according to the design. Checking
for accuracy in every job task is another part of quality control in construction.
The purpose of this paper is to provide guidance in developing quality control checklists. Checklists
are generally prepared to prevent common mistakes in daily activities. Checklists are used to assure proper
construction. Construction activity involves a regular sequence of operations which are needed to be checked at
each level. It also provides documentations of each procedures. Visual inspections, field surveys, and laboratory
testing data can be gathered using checklists. It provides an evidence, that checks has been performed by which
a system can be developed to control the function of each activity.
Keywords: Audit, checklists, improvement of quality, quality assurance.
I. Introduction
Top quality installation work cannot be achieved without comprehensive documentation of the
practicable viable and important check points at every stage of installation. It aims at creating confidence in the
customer that an industry is practicing scientific and systematic mark approach in the process of assuring quality
to their products.
It emphasizes the role of fact finding (not fault finding) and preventive action (not post mortem) on
varied non-conformities and problems that affect the quality of construction. Checklists should provide the
scope and objective of activity details, observations of non-conformance, issue of correct drawings/
specifications and availability of other technical data. In addition to this, checklists should also provide the
scope of following points: if the staff is adequately trained or not for the concerning activity, has the repaired
and reworked items re-inspected separately, and if special processes are under strict control, whether working
instructions are implemented or not, and if the equipment’s are calibrated, and also, if any balanced work
remaining before starting other works, etc.
1.1 NEED FOR STUDY
Checklist identifies common defects and the number of observed occurrences of the defects. It is a
factual tool that helps the worker to collect information regarding the defects observed.
Checklist is a tool for questioning and getting the required information to achieve the goals. Checklists are the
set of documents to help the audit. Checklist fulfills the criteria for quality assurance requirements of
construction activities. It checks activities to ensure compliance with the plans and specifications. It informs the
contractor of any work that is in noncompliance.
Application of checklists informs the contractor of deficiencies, so that corrections can be made and
retesting performed prior to covering any substandard work with additional material. Now, not only checklists
helps to produce quality, defect-free work, it also helps in developing documentation of your quality practices.
1.2 LITERATURE REVIEW
Following points emerged from the literature review:
Department of construction and infrastructure: Northern Territory Government, Australia has indicated
the following points:
It is difficult during a visit to a construction site to memorize all of the details that need to be checked and while
the obvious ones stand out, many other items that should be checked are forgotten. Superintendents may get
distracted or over extended due to time constraints and overlook items that may have more serious consequences
later in the project. Thus Check Lists provide a guide to the inspections that are required on site for a particular
project. They are a precise of the full clauses in the project specification and can be referred back to the
specification if the full text of the particular item is required. The check Lists will remind you of virtually every
potential problem in materials, workmanship and coordination between trades.

Checklists are valuable evaluation devices when carefully developed, validated, and applied. A sound
evaluation checklist clarifies the criteria that at least should be considered when evaluating something in a
particular area; aids the evaluator not to forget important criteria; and enhances the assessment's objectivity,
credibility, and reproducibility. Moreover, such a checklist is useful in planning an enterprise, monitoring and
guiding its operation, and assessing its outcomes. In the evaluation vernacular, checklists are useful for both
formative and summative evaluations.
The construction of a building requires so many things in the first place, to build a substantial strong
structure. It not only requires the best of the construction materials and personnel but also some of the important
quality control techniques on site while at the start of the construction and in between construction.
Checklists are regularly used for inspection of construction activities. Checklists are an ongoing activity to the
consultant to inspect the executed work or installations. If the work is not done as per specifications then the
work is rejected and the contractor has to rework or take remedial measures, to ensure work is executed as per
specifications.
Problems can be prevented using checklists by checking every stage of project from predesign to when
construction begins. It reduces time needed for paperwork and saves time and money on every construction job.
Checklists helps the professionals to produce the necessary documents that they need to strengthen their position
in case claims are made after a job is completed. It also helps protects the users from possible by creating a
protective paper trial.
Checklists are convenient and easy to use, also time saving and moneysaving. Checklists serves as a
guidance for all architects, contractors, developers, and engineers involved in construction activities and they are
very valuable for future reference.
1.3 METHODOLOGY OF STUDY
The study was carried out in two stages. In the first stage, a site visit checklist was designed; in the
second, its applicability and effectiveness were tested. The applicability and effectiveness of the checklist were
tested on one of the ongoing residential building project. The contractors, project managers, superintendents,
supervisors, and owners of project, were all asked to use the checklist. Before the first trial, they were
interviewed individually to confirm that they understood the contents and objectives of the checklist. They were
also asked to report items they found to be inadequate and those that they felt to be important which were not
included in the checklist. Their views were considered in preparing final format of checklist. Thereafter the
contractors, supervisors, and owners of the project filled out the final checklists for daily activities.
In the second stage, the percentage of factors that conform to the requirements are determined by dividing the
number of “non-conforming checks (NC)” by the “total number of checks (TC)” inspected and converting the
ratio to a percentage, called as NC INDEX.
Therefore
NC INDEX =
TotalNo. Of NC′
s (NC)
TotalNo. of Checks (TC)
Summary of details for all sections for which the distribution is:
a) Total no of checks (TC).
b) Total no of NC’S (NC).
Outcome of the above is the ratio in percentage indicating 2 factors. If the NC INDEX comes within 10% then
green token is issued for that activity and if the index is above 10% then red token is issued.
II. Checklist Design
The checklist is divided into four components: Equipments & tools, checks – before work, during work
and after work. Checklist items were designed to address important work and defects based on current site visit
deficiencies. It also considers frequently occurring defects, and development of the construction productivity
factors based on the system and also out of the checks carried as per classification indicated above.

Fig: 1 Framework for checklist design
Every item was again analyzed as under:
a) Number of equipment’s, capacity and supporting tools such as trowel, tray for mortar mixing, line-dori,
etc.
b) Manpower- operators, helpers with experience.
c) Checking for cleaning of area for removal of foreign material, water tightness, repairing identified
defects and damages.
d) After completion of activity-checking for leakage, slopes and any other defects.
Checklist provides a measurement of workmanship of a constructed product and respective use of processes.
Development of a complete checklist is dependent on selecting important factors from drawings, specifications,
standards, tolerances, and also manufacturing standards.
2.1 CASE STUDY
One construction site is selected for the study where the activities can be regularly monitored. The
construction site named PITTIE KOURTYARD at Kharadi, Pune-Nagar Road, Pune – 46. It complies with
three towers of G+20 floors. Client’s name is “RAJA BAHADUR INTERNATIONAL LTD”. and quality
consultant were “Construction Quality Rating Agency Pvt. Ltd. (CQRA)” and with this, material testing and
controlling has been carried out by M/S Durocrete.
Name of the Project : “Construction of Residential High Rise Towers.
Client : Raja Bahadur International Limited.
Quality Consultant: CQRA
Architect: Rajeev Sathe
Contractor: For RCC works, Sai Deep Enterprises- A&C BLDG
Mr. Takwale-B BLDG
Type of Contract: Item rate contract.
Present Status of Project: For RCC work completion of Buildings is as follows
A-45% B-40% C-35%
Location of the Site: Site is located near Pune Airport, Kharadi, Maharashtra, India.
Advanced technical features provided in the above project are:
Gas Leak Detector & Controller
Environment friendly green building registered with IGBC.
Vastu principles incorporated.
Earthquake resistant RCC frame structure.
3 high speed elevators including 1 stretcher lift
Vehicle free garden podium
Eco friendly waste management system and sewage treatment plant.
A typical checklist for “waterproofing work for toilet” was prepared and the checks been performed for the
above building by me are given below. The following checklist provides a list of all issues that need to be
considered as part of the evaluation of the project. The complete work breakdown of waterproofing is as given
in table 1 below.
Inspection methodology for quality assurance:
1. Check whether method of waterproofing is as recommended by consultant and if proper application methods
are used.
2. Check whether all the drawings with relevant details for water proofing treatment are available with the site
staff.
3. The detailed instructions of waterproofing should bear the signature of the consultant’s.

4. PVC water stoppers must be provided at the junction of all joints in the water retaining structures like tanks,
swimming pools etc.
5. The waterproofing supervision job card should be attached.

2.3 ANALYSIS AND CONCLUSION
From the above graph we can see that the NC Indices are fluctuating rapidly in the beginning of month.
As the work progresses the percentage of NC Index has fallen in 7 cases and which is below 10%. This indicates
number of conformities has increased and as a result the improvement of quality is observed. Similar data over a
period of six months can show substantial improvement in quality of work as NC Index would fall below 10%.
Like this, analysis on NC INDICES is carried out in the subsequent months and summary of same for the
entire work is reviewed and presented to respective authorities such as client, contractor etc. with instructions to
take suitable corrections on the particular activity. From the total numbers of NC INDICES we can verify
whether quality of work is really improved or still rectification is required to be done. This reflects the
improvement of quality of workmanship at the site which can easily be assessed and understood by the clients.
Thus keeping in view the above detail study of various items on a project site, the progressive improvement
graphs showing tendency to increase in number of NC INDICES less than 10% will be worked out to confirm
the system mentioned in this paper being implemented successfully and this will be done in subsequent project
work on this topic.
2.4 RECOMMENDATIONS
Checklists is a tool of quality assessment and indicates total NC indices . These NC indices should get
reduced as any project work progresses. NC index less than 10% indicates GOOD QUALITY workmanship and
such quality should be regularly implemented at large projects by engineers, contractors, clients etc.
Application of checklist should be done regularly for quality inspection, for recording specific quality data of
material and constructed work, when a site work is lacking from standardized practices. The checklists could be
used on other projects that exhibit more complications such as huge infrastructure projects. Same work can be
improved by developing and using different software’s by which quality can be easily controlled on multiple
activities. Considering this approach further study will be carried out by using application of different software’s
in subsequent project work.
