ABSTRACT This work is carried out to identify and discuss the need for a computer system in hotel business billing system. A hotel business is a hospitality industry which caters for both leisure and well being of its guest. The duties of hotels are to offer accommodation to their guest and to render services to them. These services are usually personal. The focus on this topic is to introduce computer in the allocation of rooms and billing system of a hotel. The current process of billing is...
INTRODUCTION The main objective of this essay is to examine the role played by women in commercialization of agriculture in particular in small holder production of agro exports in MeruAbothuguchi west and non traditional exports especially French beans production. Commercialization of agriculture may take different forms both involving production for domestic market and international market. Is this paper I concentrate on the input of women in output geared towards sale at the internat...
ABSTRACT Recent initiatives to add mobility to the Internet and packet data services to third generation cellular systems are being considered by emerging mobile service providers as possible candidate solutions for the delivery of IP data to mobile users. Though it has a number of shortcomings, Mobile IP represents a simple and scalable global mobility solution but is not appropriate in support of fast and seamless handover control. In contrast, third generation cellular systems are buil...
ABSTRACT This study was undertaken to assess the contributions of teachers’ knowledge of Curriculum Characteristics, value internalization and commitment, perception of adequacy of facilities, equipment and materials, and degree of performance of implementation roles/behaviours to achievements in Junior Secondary Certificate Examination in Home Economics. Effect of state and teachers’ qualification on achievement in the same examination was also assessed. The study employed ex-post facto ...
ABSTRACT This chapter describes security threats that systems face when they are connected to the Internet. We discuss their security requirements, potential security threats and di erent mech-anisms to combat these. In addition, the text presents the two most popular protocols (SSL and its successor TLS) to secure data transmitted over the Internet. Finally, we describe well-known applications such as Secure Shell (ssh) and Secure File Transfer Protocol (sftp) that provide a reasonable level...
INTRODUCTION Hajia Gambo Sawaba General Hospital since its inception in 1975 has received considerable amount of people, for treatment medical advice, family planning and a host of other reason. Different categories of people have patronized the hospital for its efficiency. It is therefore in the best interest of the researcher to use his or her knowledge of statistic application is the attendance of ill health (patients) attending the hospital. It does not and here the research as will lo...
ABSTRACTThe objective of this research is to find out the impacts of computer usage by physicians in Kano State and this is likely to increasingly replace handwritten documentation in other institutions. The population consisted of the physicians in Kano state hospitals. A questionnaire was designed and administered among 26 physicians using a simple random sampling technique. Simple percentage was used to analyze the research questions.The study found out that the physicians in Kano state ne...
ABSTRACT Wastes generally render our environment unfriendly and the worst of them all are those wastes that are non-biodegradable and as such, wastes of these forms (non-biodegradable) pose a serious threat to our environment. One of these categories of non-biodegradable wastes is pure water sachets. They are found in virtually every part of Nigeria and various attempts have been made to biodegrade these pure water sachets. One of these attempts was carried out by Nwachukwu S.et al (2010) in...
ABSTRACT The characteristics of publish/subscribe technology are of synchronism and loosely coupled. This phenomenon makes producers and consumers are de-communicated in temporal and spatial domains during processing. It requires develop a dynamic integration in today's large-scale, distributed information system. This paper introduces a Semantic Integration Data Model (SIDM) for publish/subscribe systems, within which model subscription module is designed. The model contains a matching algor...
ABSTRACT An efficient and distributed scheme for file mapping or file lookup is critical in decentralizing metadata management within a group of metadata servers. This paper presents a novel technique called Hierarchical Bloom Filter Arrays (HBA) to map filenames to the metadata servers holding their metadata. Two levels of probabilistic arrays, namely, the Bloom filter arrays with different levels of accuracies, are used on each metadata server. One array, with lower accuracy and representin...
ABSTRACT The next-generation mobile network will support terminal mobility, personal mobility, and service provider portability, making global roaming seamless. A location-independent personal telecommunication number (PTN) scheme is conducive to implementing such a global mobile system. However, the nongeographic PTNs coupled with the anticipated large number of mobile user’s in future mobile networks may introduce very large centralized databases. This necessitates research into the desig...
ABSTRACT We consider several distributed collaborative key agreement and authentication protocols for dynamic peer groups. There are several important characteristics which make this problem different from traditional secure group communication. They are: 1) distributed nature in which there is no centralized key server; 2) collaborative nature in which the group key is contributory (i.e., each group member will collaboratively contribute its part to the global group key); and 3) dynamic natu...
ABSTRACT Wireless hotspots are typically implemented using 802.11 APs. Each AP typically operates on a single, administrator-configured wireless channel. Each client associates with a single AP and subsequently interacts with this AP alone, on the AP’s configured channel. As a basic design rule, APs within radio frequency (RF) range of each other are set to different ‘non-overlapping’ channels. Proper assignment of channels to APs is important so that the network can take full advantage...
ABSTRACT Digital watermarking is the process by which identifying data is woven into media content such as images, movies, music or programming, giving those objects a unique, digital identity that can be used for a variety of valuable applications. Imperceptible to the human senses yet easily recognized by special software detectors, a digital watermark remains constant even through recording, manipulation and editing, compression and decompression, encryption, decryption and broadcast witho...
