Effect Of Catholyte Concentration On Current Production During Chocolate Industry Wastewater Treatment By A Microbial Fuel Cell, Diana Rahayuning Wulan, Suprihanto Notodarmojo

Makara Journal of Technology

Microbial fuel cells (MFCs) use bacteria as a catalyst to oxidize organic and/or inorganic substrates and produce electric currents. Wastewater could function as an electron donor in the anode chamber and, thus, represents a very promising energy source. Catholytes, as electron acceptors, influence power production in MFCs by increasing the availability of electrons. The present research aims to determine the influence of catholyte concentration on current production in an aerobic two-chamber MFC. Aerobic treatment was carried out in the two-chamber MFC operated in an incubator at 37  1 °C with and without aeration in the cathode chamber. Wastewater from ...

Hepatitis B virus (HBV) infection is one of the main causes of liver damage, which can also lead to chronic hepatitis B (CHB) infection. More than 240 million individuals worldwide are chronic carriers of HBV. Among individuals with CHB who are untreated, approximately 15% – 40% will progress to liver cirrhosis or cancer. The interactions between HBV and host immune response play significant roles in the progression of CHB. CHB can be generally divided into four different clinical phases: immune tolerance (IT), immune clearance, inactive carrier, and Hepatitis B surface antigen (HBsAg)-negative reactivation phase (ENEG). Many studies showed that interleukins ...

Redesign Of Product Packaging With Kansei Engineering: Empirical Study On Small-Medium Enterprises In Indonesia, Amalia Suzianti, A. Aldianto

Makara Journal of Technology

Small-medium enterprises (SMEs) in Indonesia have been proven to be one of the important pillars of the national economy. Unfortunately, some problems hinder their development, and one of the critical problems is the quality of product packaging. The packages of SME products are considered poor, dirty, and unattractive. Packaging problem is one of the factors why consumers are less interested in buying and why SME products always lose in the competition with other products. This study discusses how to employ Kansei engineering to design better SME product packaging with a focus on psychological (affective) aspects. This research concludes that there ...

In the blooming era of smart edge devices, surveillance cam- eras have been deployed in many locations. Surveillance cam- eras are most useful when they are spaced out to maximize coverage of an area. However, deciding where to place cam- eras is an NP-hard problem and researchers have proposed heuristic solutions. Existing work does not consider a signifi- cant restriction of computer vision: in order to track a moving object, the object must occupy enough pixels. The number of pixels depends on many factors (how far away is the object? What is the camera resolution? What is the focal length ...

Managing Redundancy And Conflicts In Distributed Firewalls, Ms. Kruthi K. Kumar

International Journal of Computer Science and Informatics

The use of firewall has been widespread in all the emerging technologies such as Service Oriented Architecture, web services, cloud computing and so on. The term security itself is the most important task that has to be maintained in the real-time applications. Policies are enrolled in the security of the firewall where the quality of policies is to be maintained. The network administrator defines the policy as a rule. Managing the firewall policies, maintaining the risk analysis and also the conflicting nature that arise in the network, lack of systematic analysis mechanisms and tools used are often error prone. The ...

Increasing Accuracy Of K-Nearest Neighbor Classifier For Text Classification, Falguni N. Patel

International Journal of Computer Science and Informatics

k - Nearest Neighbor Rule is a well-known technique for text classification. The reason behind this is its simplicity, effectiveness, easily modifiable. In this paper, we briefly discuss text classification, k-NN algorithm and analyse the sensitivity problem of k value. To overcome this problem, we introduced inverse cosine distance weighted voting function for text classification. Therefore, Accuracy of text classification is increased even if any large value for k is chosen, as compared to simple k Nearest Neighbor classifier. The proposed weighted function is proved as more effective when any application has large text dataset with some dominating categories, using experimental ...

Ocl Formal Specification Based Metrics As A Measure Of Complexity And Fault-Proneness, A. Jalila, D. Jeya Mala, S. Balamurugan, K. Sabari Nathan

International Journal of Computer Science and Informatics

Formal specification of UML models in OCL is essential to improve software quality. Owing to the use of OCL in precise model specification, its application has been looked in different perspectives such as early measurement of module complexity. Moreover, when UML class diagrams are complemented with OCL, the metrics collected from OCL specification can serve as an indicator of fault-prone components. In the proposed approach an empirical study has been conducted on five soft real time case study applications. In this paper, existing metrics which are applicable to OCL expression are validated using module complexity. Moreover, a new metrics suite ...

Dynamic Slicing Of Aspect-Oriented Uml Communication Diagram, Alina Mishra, Subhrakanta Panda, Dishant Munjal

International Journal of Computer Science and Informatics

Aspect-oriented Programming (AOP) is a recent programming paradigm that focuses on modular implementations of various crosscutting concerns. The typical features of AOP such as join-point, advice, introduction, aspects etc. make it difficult for applying slicing. Program slicing is a method to extort statements that are relevant to a particular variable. Program slicing, as initially defined by Weiser is based on static dataflow examination on the flow graph of the program. Program slicing has been applied in parallel processing, program debugging, program integration,program understanding , software testing and maintenance etc.In this paper, we proposed a technique for dynamic slicing of ...

Aspect Mining Using Uml Communication Diagram, Subhrakanta Panda, Alina Mishra, Dishant Munjal

International Journal of Computer Science and Informatics

Aspect-Oriented Programming (AOP) focuses on precise constructs for modularization of the crosscutting concerns of a program. Crosscutting concerns can be defined as the functionalities that navigate the principal decomposition of software and therefore cannot be assigned to a single modular unit. Aspect mining attempts to find and isolate crosscutting concerns dwelling in legacy systems which in turn help in the adoption of an aspect-oriented design. Functionalities originally scattered across different modules and tangled with each other can be factored out into a distinct, separate unit, called an aspect. Identifying and refactoring the existing system into AOP considerably ease the debugging ...
