A rigorous user needs experience evaluation method based on software quality ...TELKOMNIKA JOURNAL
Our lives, nowadays, are digital. We, as humans, are using software applications in all our life aspects to meet our daily objectives and fulfill our needs. Software solutions that comprise mobile apps are widely spread, users can select from hundreds of available software solutions that fit their needs. Accordingly, user needs are becoming intricate and the software organizations are competing high to satisfy user requirements and the desires for better quality. This competition is not about satisfying the functional requirements but also satisfy user experience as well. Accordingly, studying, measuring, and improving user experience is crucial for the success of any software product. This research focuses on evaluating user experience needs by developing user experience needs evaluation method based on three main disciplines the user experience framework, the evaluation theory concept, and the ISOsoftware quality standards ISO/IEC 25022 and ISO/IEC 25023. Although these disciplines are available in the literature, they are not linked together to complete the mosaic picture of developing a UX evaluation method. Linking there three disciplines led to systematically identify the necessary evaluation criteria to evaluate user needs experience.

Study on Validation of Wholesaler Selection of Personal Protective Equipment ...ijmvsc
Most of the construction organizations in India rely on personal protective equipment (PPE) to reduce
/avoid accidents at workplace instead of adopting engineering and administrative controls, and selecting a
wholesaler is an important decision making process, as quality of PPE is of paramount importance in
avoiding accidents. The wholesaler selection is crucial particularly for construction organizations involved
in execution of works in remote areas like construction of thermal electric plants, highways, buildings etc.
It is difficult to find wholesalers in the vicinity of workplace. As construction organizations are more
dependent on wholesalers, the direct and indirect consequences of poor decision making is more severe, as
non standard/poor quality PPE results into injuries and sometimes fatal accidents also occur. In the
present study, a wholesaler selection model using Integer linear programming (ILP) for multi product and
multi wholesalers has been proposed, and the model is validated in a construction organization in which
the process of purchasing is centralized. The construction organization was involved in execution of
various construction activities at four different sites in northern region of India.
PROPERTIES OF A FEATURE IN CODE-ASSETS: AN EXPLORATORY STUDYijseajournal
Software product line engineering is a paradigm for developing a family of software products from a
repository of reusable assets rather than developing each individual product from scratch. In featureoriented software product line engineering, the common and the variable characteristics of the products
are expressed in terms of features. Using software product line engineering approach, software products
are produced en masse by means of two engineering phases: (i) Domain Engineering and, (ii) Application
Engineering. At the domain engineering phase, reusable assets are developed with variation points where
variant features may be bound for each of the diverse products. At the application engineering phase,
individual and customized products are developed from the reusable assets. Ideally, the reusable assets
should be adaptable with less effort to support additional variations (features) that were not planned
beforehand in order to increase the usage context of SPL as a result of expanding markets or when a new
usage context of software product line emerges. This paper presents an exploration research to investigate
the properties of features, in the code-asset implemented using Object-Oriented Programming Style. In the
exploration, we observed that program elements of disparate features formed unions as well as
intersections that may affect modifiability of the code-assets. The implication of this research to practice is
that an unstable product line and with the tendency of emerging variations should aim for techniques that
limit the number of intersections between program elements of different features. Similarly, the implication
of the observation to research is that there should be subsequent investigations using multiple case studies
in different software domains and programming styles to improve the understanding of the findings.

A study on the applicability of quality circles to construction projectseSAT Journals
Abstract There is a rising need for infrastructural development in the city of Bangalore. As there are over 800 construction, civil engineering, building and development firms in and around the city, there is high competition. One of the factors which proves to be imperative in giving a competitive edge to these firms is good quality of their work among others like improved productivity and timely completion of their projects. Quality circles (QC) have been found to be a simple and productive technique of Total Quality Management (TQM) , despite having low cost of quality. Although QC is native to the production industry, it has been proposed to be implementable in construction industry. QC’s have never reportedly been used in the Indian construction industry. As the construction industry is significantly different from the production industry and the Indian organisational culture is also very different as compared to many countries like Japan where QC’s thrive, this paper seeks to analyse and study the applicability of QCs as an efficient TQM method to construction projects in and around Bangalore city. This paper seeks to accomplish this by highlighting the favourable conditions and hindrances that application of QC’s might face in Indian construction industry. The research methodology includes a detailed literature review and a questionnaire survey. The data was analysed using Index Average Method and percentage representations, both accompanied by descriptive analysis. Based on the analysis of the data obtained from the survey it was concluded that the Indian construction industry possesses various conditions which prove to be highly favourable towards the application of QC, however the temporary nature of the teams formed on construction projects, and the present organisational culture which might not support participative management have been found to be questionable conditions, which require improvement. Key Words: Quality Circles (QC), Total Quality Management (TQM), Participative Management, and Facilitator

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

MULTI ATTRIBUTE DECISION MAKING FOR MOBILE PHONE SELECTION Sandeepak Saket1, Vidyapati Purbey2, Jagadish3, Amitava Ray4 1B.Tech, Mechanical Engineering, NIT Silchar, Assam, India 2B.Tech, Mechanical Engineering, NIT Silchar, Assam, India 3Assistant Professor, Mechanical Engineering, NIT Silchar, Assam, India 4Assistant Professor, Mechanical Engineering, NIT Silchar, Assam, India Abstract In current scenario the role of mobile is essential for the new generation people and for new system. A systematic and efficient approach towards selection of mobile is necessary for a commons people. To fulfil need of customer in the mobile areas is challenging task for the designer. The objective of this paper is to selecting the suitable mobile by taking cost as constraint. In this paper multi attribute decision making method (MCDM) i.e. QFD approach has been used for selection of appropriate mobile to the commons people. In selection of the mobile people find difficulties due to multiple attributes/criteria. In this study, the customer requirements are taken as input and appropriate technical requirements has been computed using Quality Functional Deployment (QFD). The validation of the proposed methodology is illustrated by a real life case study. Keywords: QFD, MCDM, Mobile Selection
-----------------------------------------------------------------------***----------------------------------------------------------------------- 1. INTRODUCTION QFD is the customer driven tool in implementing TQM (total quality management) And it provide means of translating customer requirement to technical requirement for each stage of the engineering application. In present scenario application of the mobile play an important role to connect the people throughout the world. In present scenario due to the competition all mobile company are bringing many varieties of mobile into the market within less time with addition of good feature from one version to another and at high cost as well as at low cost. In present scenario most of the industry focusing on profit of their business industries are increasing feature day to day so cost is also increasing this make suffer to poor people hence which necessities in the implementation of methodology in selecting an optimal mobile among several choice for the middle class peoples. Which makes present generation common people difficult in selecting the appropriate mobile among the verities of available choice even for the designer to make the mobile to the customer satisfaction is a difficult task and for all the mobile manufacturing industries. Selection of the common people is MCDM (multi criteria decision making) problem for entire mobile industry which involves many input/output criteria and alternative.
Many researcher has been worked in selection area like Bhattacharya et al. (2005) integrating AHP with QFD for robot selection under requirement perspective, Wang and Chen (2012) using QFD for collaborative product design and optimal selection of module mix, Prasad and Chakraborty (2103) a quality function deployment based model for material selection, Rao R.V.(2006) a material selection model using graph theory and matrix approach, Rajesh and malliga (2013) supplier selection based on AHP QFD methodology, M. Bevilacqua et al. (2006) a fuzzy QFD approach to supplier selection, journal of purchasing and supply management, S.H. Ha, and Krishnan (2008) a hybrid approach to supplier selection for the maintenance of competitive supply chain, expert system with application. In mobile phone many researcher like Isiklar and Buyukozkan (2007) using a multi- criteria decision making approach to evaluate mobile phone alternatives, Zheng and pull (2007) Improving mobile service design a QFD approach, Xin et al. (2013) robust passive auto focus system for mobile phone camera application, O. Jiyong et al. (2013) selective generation of gabor feature for fast face recognition on mobile device, Jaeminchun (2011). A method for searching photos on a mobile phone by using the fishey view technique, ElieKhoury et al. (2013) Bi- model biometric authentication on mobile phone in challenging conditions, W. Chianghong et al. (2010) Taiwanese 3G mobile phone demand forecasting by SVR with hybrid evolutionary algorithms, Eekanbayraktar et al. (2012) measuring the efficiency of customer satisfaction and loyalty for mobile phone brand with DEA.
From the literature review it is found that, no researcher has been worked in the area of mobile selection for the common people using QFD approach. In this paper local survey has

been carried out at NIT Silchar place Fakir Tilla for collecting the customer requirements for QFD matrix.
The following section explained in this paper as follows: Section.Error! Bookmark not defined., Section.3 discussion and detailed case study i.e. validation of case study is discussed, Section.4 result and discussion has been discussed. Finally reference has been explained in last section. 2. HOUSE OF QUALITY The primary planning tool used in QFD is the house of quality. The house of quality translates the voice of the customer into design requirements that meet specific target values and matches that against how an organization will meet those requirements. Many managers and engineers consider the house of quality to be the primary chart in quality planning.
The structure of QFD can be thought of as a framework of a house, as shown in Fig- 1
Fig- 1 House of quality The parts of the house of quality are described as follows:
1. The exterior walls of the house are the customer requirements. On the left side is a listing of the voice of the customer, or what the customer expects in the product. On the right side are the prioritized customer requirements, or planning matrix. Listed are items such as customer benchmarking, customer importance rating, target value, scale-up factor, and sales point.
2. The ceiling, or second floor, of the house contains the technical descriptors. Consistency of the product is provided through engineering characteristics, design constraints, and parameters.
3. The interior walls of the house are the relationships between customer requirements and technical descriptors. Customer expectations (customer requirements) are translated into engineering characteristics (technical descriptors).
4. The roof of the house is the interrelationship between technical descriptors. Trade-offs between similar or conflicting technical descriptors is identified.
5 The foundation of the house is the prioritized technical descriptors. Items such as the technical benchmarking, degree of technical difficulty, and target value are listed.
2.1 Building a House of Quality Step 1: List Customer Requirements (WHATs) Step 2: List Technical Descriptors (HOWs) Step 3: Develop a Relationship Matrix between WHATs and HOWs Step 4: Develop an Interrelationship Matrix between HOWs Step 5: Competitive Assessments 2.2 QFD Approach Concept of QFD Process for Mobile Selection
In the mobile service industry the QFD approach can be implemented throughout mobile service design and development stages a generic framework for application of QFD in the mobile service is given in

Fig- 2 Generic framework for QFD application in mobile service industry
In (
Fig- 2) there are five stages for mobile service development and deployment process. The five stages are explained in details as fallows.
Survey: In the first step survey is conducted among the various people of villager near the nit and find out the view of villager toward the mobile of any company and find out which quality of mobile give more satisfaction to villager.
VOC Identification: Voice of the Customer (VOC) is a term that describes your customer’s feedback about their experiences with and expectations for your products or services. VOC is a multi-source information tool that focuses on customer needs, expectations, and product improvement. The voice of the customer is best heard as an ongoing conversation. The key to creating an effective VOC

program is to gather and use information in a timely way that helps you to improve. Organizations often have multiple touch points with the customer that occur all across the organization, including sales, support, warranty, and accounting interactions. Due to VOC we are able to find out the following thing:
o The needs and wants of customers
o The relative importance of features and benefits associated with product
o The expectations and promises that are both fulfilled and unfulfilled by product or service
o What customers need for increased satisfaction?
Technical characteristic: Those characteristics of equipment that pertain primarily to the engineering principles involved in producing equipment possessing desired military characteristics; e.g. for electronic equipment, technical characteristics include such items as circuitry as well as types and arrangement of components. Cell phone technical specifications are the main technologies that the phone employs to perform such functions as receiving a signal, accessing and downloading data or accepting different software applications. The expression also applies to basic information such as cell phone dimensions, weight, etc. some of the general technical characteristic is as follows:
a) Loudspeaker
b) Memory/space
c) Bluetooth
d) Battery
Checking of technical characteristics in mobile: In this step we check proper software and hardware in the mobile which fulfil the village need.
Selection of proper mobile: This is the final step for mobile selection for villager in this step we find out the best mobile company among the shortlisted mobile company which give more satisfaction level to the villager according to their need.
