Web service is a communication protocol and software between two electronic devices over the Internet. It extends the World Wide Web infrastructure to provide the methods for an electronic device to connect to other electronic devices. With the rapid development of the Internet and the increasing popularity of electronic payment in web service, Internet fraud and web security have gradually been the main concern of the public. Phishing is an illegal activity wherein people are misled into the fake sites by using various fraudulent methods. Web Phishing is a way of such activity, which uses social engineering technique through short messages, emails, and other social media to induce users to visit fake websites to get sensitive information like their private account, token for payment, credit card information, and so on. Hence it leads to information disclosure and property damage. As the technology advances, it needs a better model to secure people from such cyber attack.

In an attempt to lower the amount of energy consumed in order to make a significant savings in the cost of using electricity in students’ hostels, a system that monitors, controls, and manages energy usage is of paramount importance. In this paper, excess usage of electrical energy has been identified in Mandela hostel, Sharda University, Greater Noida, India, and the automation system aims at conserving this wasted energy is proposed. The system involves the use of motion sensors, ultrasonic sensors, as well as hybrid sensors placed at strategic places in the building to monitor and control light loads such as lamps, ceiling fans, and, exhaust fans, Programmable Logic Controllers (PLC), connected to a Molded Case Circuit Breakers (MCCB) of the Distribution Boards (DBs) of each floor in the building to control Air Conditioners and Water Heaters, A SCADA system which runs on a Personal Computer located in a control room to monitor and control the PLCs at each DB through a Master PLC. The energy consumption of the Hostel before and after the implementation of the proposed automation system has been calculated. Based on the comparison made, 45% of the total amount of energy consumed before the automation can be conserved, this amount to huge savings and gross reduction in the wastage of the scarce resource of electricity.

Waste disposal are a part of our everyday life and mostly its condition are improper managed due to improper waste dumping, collection and management, which leads in foul smell and unhygienic condition, thus inherently results in pollution of the environment. Therefore, in this research, design and implementation of Smart Waste Bin with monitoring system is proposed utilizing the ongoing innovation of automation and GSM. The ultrasonic sensor in the bin persistently screens the level of the waste in the bin and communicates to the waste administration organization when the bin filled and the Ultrasonic sensor is also used to open and close the cover of the bin whenever persons are nearby the bin. Thus the research has better level of smartness compared to existing ones in metropolitan cities in a centralized manner.

The main objective behind the development of this robot is for the surveillance of human activities in the war field or border regions in order to reduce infiltrations from the enemy side. The robot consists of night vision wireless camera which has the function of transmitting the videos of the war field in order to prevent any damage and loss to human life. Since we know military people have a huge risk on their lives while entering an unknown territory so the robot will serve as an appropriate machine for defense sector for the reduction of the loss of human life and will also prevent illegal activities. It will pass the information with the help of all the military people and armed forces to know the condition of the territory before entering it. The robot has the aptitude of detecting the buried mines and ability of letting the user control it wirelessly in order to avoid human causalities. The robot can even act as a path guider in normal case and as a fire extinguisher in emergency. The robots are so designed as it easily detects fire, before it rages out of control, can one day work with firefighters greatly reducing the risk of injury to victims.

Agriculture has proven to be the most sustainable and reliable source of livelihood for the human race. This is due to the eco-friendly processes involved in crop and animal production and their regenerative nature. Rodent and bird pests constitute major source of losses in farming; existing pest control methods pose environmental and health challenges to humans and the entire ecosystem, hence the need to develop a more efficient, human and eco-friendly system for the control of pests. This work focuses on the design of a solar powered automatic pest control system that will employ the three basic signals of motion, sound and light as deployed by humans to scare rodent and bird pests from the farm.

The aim of this investigation was to determine the prevalence rate of endoparasite helminthes in two breeds of goats, West Africa Dwarf (WAD) and Red Sokoto (RS), in the study area. Out of 532 faecal samples examined from slaughtered goats in three abattoirs (Atakpa, Anantigha, and Ikot Eno Obong) in Calabar, 413 (77.6%) were infected with helminth parasites. Red Sokoto goats were more infected (78.35%) than West Africa Dwarf goats (73.2%). The total mean faecal egg counts was highest in Red Sokoto goats 163±10.72, compared to 146.7±11.38 recorded in WAD goats. The three helminthes recovered from 413 faecal samples of goats were Haemonchus contortus, Trichuris trichiura and Taenia spp. H. contortus had the highest prevalence rate of 49.4%, compared to T. trichiura 20.3% and Taenia spp 7.9%. Female goats were more infected (82.6%) as against 77.9% in males. Female goats had higher total faecal egg counts of 155.2±3.33 than 127.2±3.01 in male goats. It was found that adult goats were more infected (89.6%) than young ones (75.5%). Months and season have influence on the infection rate of parasites on goats. H. contortus prevalence was highest (26.1%) in September, while seasonal prevalence was highest (42.1%) in late rainy season. In this study, since more RS goats were infected than WAD goats, it was recommended that small ruminant goat farmers should concentrate more in the farming of WAD goats because of their resilience to parasitic infection than RS goats, in the study area.

In the world today, web is presently going ahead from text information to media information; one of the significant security concerns is the assurance of this multimedia information. Image, which covers the most elevated level of the multimedia information, its security is significant. This can be accomplished by Image encryption. This paper contribution is geared towards securing image transmission using digital signature of the original image by encoding version of original image, the encoding of the images is done using an error control code. The goal of this paper is to develop a system that uses a symmetries method (Encryption and Decryption) for an image and also platform that convert image into string (Alphanumeric Strings). The technique used is digital Signature which enables the recipient of a message to authenticate the sender of a message and verify that the message is intact and it creates new symmetric block encryption schemes. An error control code is determined in real-time on the size of the original image.

In the present investigation, post combustion techniques are adopted for existing diesel engine to reduce the emissions. Two after treatment devices viz; diesel particulate filter (DPF) and diesel oxidation catalyst (DOC) were fixed at exhaust pipe of engine; and urea solution and Di-Ethyl Ether (DEE) are injected separately. Experiments were conducted on a four stroke single-cylinder, water cooled compression ignition engine. All tests were conducted at different loads viz. 4kg and 6kg load. The engine speed is maintained constant at 1380 rpm. Diesel engine has bore 80mm, stroke 110mm, running at 1380 rpm has compression ratio 16:1, rated power 3.68 KW. CO emission reduced by 36% combining DPF, DOC and injecting urea solution. NOx emission reduced by 15% when DPF and DOC are combined and reduced by 30% when urea solution is injected. HC emission reduced by 9% when DEE is injected in exhaust pipe with DPF and DOC. Overall comparison of all the results, it can be concluded that the least emission level was observed when engine is operated at 4kg load and having combined DPF, DOC and injecting urea solution. At this condition, the emissions values are CO 0.5%, HC 53 ppm, NOx 446 ppm. Hence, there is need for combined DPF, DOC and urea solution injection at the exhaust pipe for an existing diesel engine.

The government website is a thing that people will know on what is happening with that certain government office and what would be the information a citizen can get with that website. Disseminating of information nowadays is delivered through websites. Government websites can indicate its contact number in case there are users who want to ask questions from a certain government office. It could also indicate the image of the website if what is that website looks like and can also put its address too. However, there are some existing websites developed without considering the user's needs and didn't meet the expectations of the users maybe because it is not easily accessible to all kinds of users. We conducted this research to determine if the government websites are accessible and more effective and efficient. Moreover, the purpose of conducting this study is to know the citizens perception about the 5 websites that are examined. In the result, the mean of the level of usability of the government websites is 4.2158 with a standard deviation of 0.57193. This shows that the level of usability of the government websites is very high while the mean of the level of accessibility of government website is 4.1940 with a standard deviation of 0.59177. This shows that the level of accessibility of government website is high. It has also found out that among the indicators of the usability of government websites, efficiency and satisfaction are the two predictors of the accessibility of government websites. The result of some selected websites followed the consideration on usability and accessibility that is necessary for the existing and future government websites that can be found within Davao region.

Construction waste management at all stages of construction process is a major concern in the construction industry because of the strife to improve performance in terms of cost, quality and sustainability. Ineffective material management add to cost of storing and transporting of construction waste, along-side loss of revenue from not reclaiming waste materials, knowing its financial implication precede construction companies to take actions in minimizing waste. In other words this will creates an atmosphere conducive enough to solving materials user supplier problems in terms of reduction in cost of materials, better quality control and improved labour productivity. As such the aim of this paper is to assess construction waste management application in building projects, with specific objectives of assessing material management practice by construction firms, to also identify the factors militating against materials management, to asses impact of waste on building projects performance, and to find out measure for effective material management. Fifty (50) questionnaires were administered to professionals including architects, builders, civil engineers, quantity surveyors, and other professional’s engaged in the process and production of building element. Frequency, mean and standard deviation was used for the analysis. The study identified receiving and verification of materials on site, possession of qualified staff and Possession of required equipment as major factors militating against materials management. Also construction wastes creates environmental and health problems, waste consumes resources and time without adding value to the client and wasteful activities in building projects reduce the contractors’ profit margin are those factors which have high impact on building project performance. In addition Timely placing of orders for materials, Ensuring quality assurance and control processes are in place and making the store safe from theft and vandalism are the major measures required for effective material management for building project. It is therefore recommended that there should be awareness programs for all construction companies on construction materials management and handling. Also formal education should be given to storekeepers and the foremen on effective materials handling systems.
