Hotspot in UTP

In today's world, it is necessary for organizations especially educational institution to keep up with the latest trend in technology. Technology changes practically everyday and it is important for these organizations to explore the world of technology. The latest hit on the market will be the Wi-Fi (wireless fidelity) fewer. Hotspot is created using this Wi-Fi technology. Hotspot is a specific geographic location in which an access point provides public wireless broadband network service to mobile visitors through a WLAN. The main objective of this project is to do a research on hotspot and establish a wireless environment to support the theories provided in this documentation. This facility is provided for those with laptops and PDAs with wireless PC Card attached to them. Their machines will be free from any cables or wires connecting to the network port. They are basically mobile users and wireless LAN is ease to use as special terminal or OS is not required to access the network. In the methodology chapter, author discuses on the stages of development cycle used in conducting the study and research on the project. The results and findings discuses on authors conclusions and research diversion regarding the effort on establishing a hotspot in UTP. Author indicates the succession of the research in forming a wireless environment and the factors involved in setting up the Hotspot. The conclusion discusses on authors achievement in implementing hotspot and also the future upgrades suggested by author herself in order to improvise the research study in future

Differential Adoption of Cloud Technology: A Multiple Case Study of Large Firms and SMEs

Firms across the industry segments have been exploring cloud computing to derive benefits out of its technological features. Even though literature pertaining to cloud adoption by firms exists, the factors based on cloud-specific characteristics are mostly anecdotal in nature. Following a multiple case study approach, we identify factors specific to cloud technology adoption by firms. We further explain the differential adoption of the cloud between large and small firms. Overall we obtained 11 variables that differentiate large firms and SMEs in their adoption behaviour. We further contribute to theory by mapping the extracted variables of cloud adoption to Diffusion of innovation theory (DOI) and Technology organization Environment framework (TOE)

First record of redneck goby Schismatogobius deraniyagalai (Teleostei: Gobiidae) from Seethanathi river, Karnataka, Southern India.

Schismatogobius deraniyagalai is recorded from the Seethanathi River of Karnataka state in the southern part of India. Previous records of these species were from the streams in Kerala of India and from freshwater habitats of Sri Lanka. Herein we report the occurrence of this species in Seethanathi River showing its distribution extended further north along the west coast of Peninsular India

A Comprehensive Review of Recent Variants and Modifications of Firefly Algorithm

Swarm intelligence (SI) is an emerging field of biologically-inspired artificial intelligence based on the behavioral models of social insects such as ants, bees, wasps, termites etc. Swarm intelligence is the discipline that deals with natural and artificial systems composed of many individuals that coordinate using decentralized control and self-organization. Most SI algorithms have been developed to address stationary optimization problems and hence, they can converge on the (near-) optimum solution efficiently. However, many real-world problems have a dynamic environment that changes over time. In the last two decades, there has been a growing interest of addressing Dynamic Optimization Problems using SI algorithms due to their adaptation capabilities. This paper presents a broad review on two SI algorithms: 1) Firefly Algorithm (FA) 2) Flower Pollination Algorithm (FPA). FA is inspired from bioluminescence characteristic of fireflies. FPA is inspired from the the pollination behavior of flowering plants. This article aims to give a detailed analysis of different variants of FA and FPA developed by parameter adaptations, modification, hybridization as on date. This paper also addresses the applications of these algorithms in various fields. In addition, literatures found that most of the cases that used FA and FPA technique have outperformed compare to other metaheuristic algorithms

The management of e-waste in KwaZulu-Natal.

Thesis (M.Com.)-University of KwaZulu-Natal, Westville, 2010.Information Technology is seen as that which makes one's life easier, fun and more comfortable. When a new cellular phone is launched one is eager to see what the new phone has to offer, and often one convinces oneself that the new device is required. This study investigates what happens to redundant or obsolete electronic devices like cellular phones, computers and other electronic devices. Are these devices stored, donated, thrown out with the garbage or are they recycled? Information from academic sources and from all types of media, including television, print and electronic was searched to enhance the survey that was undertaken. Both the informal and formal sectors of recycling were investigated. A questionnaire was used to supplement the information found in different kinds of sources. The collected data was interpreted through the use of SPSS. Descriptive as well as inferential statistics was used to draw conclusions and make inferences. An investigation into legislation controlling the disposal of e-waste is included in this study. International, national, provincial and local government legislation is outlined. The objectives of recycling electronic waste are listed together with the challenges that face the pro-recyclers. The quantitative research methodology approach has been employed for this research. A key technique used in this study is the Research Onion. Data analysis and interpretation are based on the p-value, Pearson's chi-square and Spearman's correlation. The study has really been an eye opener in that it considers the “darker side” of Information Technology. The “darker side” of Information Technology refers to the disposal of obsolete or broken electronic devices in a manner that is harmful to the environment. The cost or lack of profit is the main driving force for incorrect disposal methods. This study has found that the best method of disposal is the take back system, where manufacturers of electronic devices are responsible for the safe disposal of the devices that they manufactured

Examining Gender Inequality in the Sri Lankan Accounting Profession

The purpose of this study is to examine the current state of gender inequality in the Sri Lankan accounting profession. Specifically, the study examines whether a glass ceiling (invisible simulated barrier) exists and whether such perception differs based on the gender. Data were gathered through structured questionnaires among 100 accounting professionals. The study found that there is no evidence to support that there is a glass ceiling for women in the accounting field in Sri Lanka. However, the study identified that even though the gender inequality has been reduced, perception on glass ceiling varies between males and females. Keywords: Gender inequality, Glass ceiling, Accounting profession, Sri Lanka. DOI: 10.7176/EJBM/11-33-02 Publication date: November 30th 201

A unique 3D nitrogen-doped carbon composite as high-performance oxygen reduction catalyst

The synthesis and properties of an oxygen reduction catalyst based on a unique 3-dimensional (3D) nitrogen doped (N-doped) carbon composite are described. The composite material is synthesised via a two-step hydrothermal and pyrolysis method using bio-source low-cost materials of galactose and melamine. Firstly, the use of iron salts and galactose to hydrothermally produceiron oxide (Fe₂O₃) magnetic nanoparticle clusters embedded carbon spheres. Secondly, magnetic nanoparticles diffused out of the carbon sphere when pyrolysed in the presence of melamine as nitrogen precursor. Interestingly, many of these nanoparticles, as catalyst-grown carbon nanotubes (CNTs), resulted in the formation of N-doped CNTs and N-doped carbon spheres under the decomposition of carbon and a nitrogen environment. The composite material consists of integrated N-doped carbon microspheres and CNTs show high ORR activity through a predominantly four-electron pathway.Ramesh Karunagaran, Tran Thanh Tung, Cameron Shearer, Diana Tran, Campbell Coghlan, Christian Doonan, and Dusan Losi
