ABSTRACT In this paper, a non–linear mathematical model is proposed to study the effects of irresponsible infected immigrants on the spread of HIV/AIDS in a heterogeneous population with a constant recruitment of susceptible receptors. Theequilibrium points, stability analysis, and numerical solution on the model are presented. The Routh–Hurwitz stability condition was employed to examine the stability of the disease– free equilibrium and Next Generation matrix was adopted to g...

Data happens to be the key concern in data mining. With the huge online data generated from several sensors, Internet Relay Chats, Twitter, Face book, Online B...
Abstract Pattern recognition is seen as a major challenge within the field of data mining and knowledge discovery. For the work in this paper, we have analyzed a range of widely used algorithms for finding frequent patterns with the purpose of discovering how these algorithms can be used to obtain frequent patterns over large transactional databases. This has been presented in the form of a comparative study of the following algorithms: Apriori algorithm, Frequent Pattern (FP) Growth algorith...
Abstract Concepts like gentelligent products, smart objects or cyber-physical systems have already proven a high potential especially for decentralized production planning and control. In this context, decentralized communication, new sensor technologies and the increased application of simulation and monitoring systems lead to an enormous increase of manufacturing data. Additionally, a new approach for the assessment of manufacturing quality based on process signals from the machine tool is ...
ABSTRACT In order to search for alternative control methods to synthetic pesticides, the potential of essential oils from Allium sativum (L.) (Alliaceae); was evaluated as fumigants against Callosobruchus maculatus (fab.) (Coleoptera: Bruchidae), a pest that attacks pulses during storage. Chickpea seeds were infested with 10 pairs of newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essential oils of garlic/l of air. The essential oils of garlic were analyzed by GC-MS. The majo...
ABSTRACT Understanding the spatial variation of urban heat Islands (UHI), will be helpful in urban micro climate studies. This study the urban heat islands of Kaduna metropolis, Nigeria. For the present study Landsat ETM+ images of 2001, 2006, 2009 and OLI 2015 was obtained from USGS of the study area. Normalized Difference Vegetation Index (NDVI) image was developed. The digital number of thermal infrared band is converted in to spectral radiance using the equation supplied by the Landsa...
INTRODUCTION This is the good Bio-Technology project on "development of biochemistry liquid stable reagents used for the estimation of Sodium and Potassium electrolytes in blood serum", which covers study based on Sodium and Potassium reagents. Chemical pathology (more commonly known as clinical biochemistry or clinical chemistry) is the area of pathology that is generally concerned with analysis of body fluids and extracts and will be used in this report This research study is based on S...
Abstract A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user, a sort of smart card that is wearable on a finger. Sun Microsystem´s Java Ring was introduced at their Java One Conference in 1998 and, instead of a gemstone, contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built by Dallas Semiconductor. Workstations at t...
ABSTRACT Street food vending has become an important public health issue and a great concern to everybody. This is due to widespread of food borne diseases, due to the mushrooming of wayside food vendors who lack an adequate understanding of the basic food safety issues. Major source contributing to microbial contamination are the place of preparation, utensils for cooking and serving, raw materials, time and temperature abuse of cooked foods and the personal hygiene of vendors. Various stu...
Planet earth is being endangered by anthropogenic activities ranging from industrial activities to seemingly innocous activities such as use of herbicides on farms.There are possibilities that the resources of the earth may not be sufficient to sustain the needs of future generations.There are also possibilities that the earth may become in conducive for human habitation due to emission of dangerous gases and...
ABSTRACT Climate change has been identified as one of the greatest challenge by all the nations, government, business and citizens of the globe. The threats of climate change on our green planet ‘Earth’ demands that renewable energy share in the total energy generation and consumption should be substantially increased as a matter of urgency. Nigeria’s energy development programme has been put under severe pressure with the ever-increasing demand supply gap. Due to predominance of fossil...
Time lapse seismic which geophysicists often abbreviate to four dimensional (4-D) seismic is a geophysical technique which involves simply repeating a series of 3-D seismic survey over time such that the fourth dimension is in “Calendar Time”. This gives it the ability to image fluid flow in a well volume.
Fibre optic technologies came out of military and space research and development programme. Until recently, glass chemistry and laser interrogation hardware have not been at a level of robust where systems could survive in down-hole environments for long periods. Because of the physical properties, glass can thrive as a sensor at extremely high temperatures and efficiently high temperatures and efficiently transmit large quantities of data where as in the past, one may have been limited to a ...
Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional events. With this in mind, it is necessary to draw out relationships between deposition...
Forensic geophysics can be seen as that involving the use of geophysical methods in the search, locating and mapping of hidden or buried features underground or underwater. Geophysical methods have the potential to aid the search and recovery of a target because they can nondestructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target or object is hidden in the subsurface.
