Multivariate Approach to Time Series Model Identification

ABSTRACT  This work suggests an exact and systematic model identification approach which is entirely new and addresses most of the challenges of existing methods. We developed quadratic discriminant functions for various orders of autoregressive moving average (ARMA) models. An Algorithm that is to be used alongside our functions was also developed. In achieving this, three hundred sets of time series data were simulated for the development of our functions. Another twenty five sets of simul...

Optical, Solid State and Structural Characterization of Optimized Grown Thin Films and their Possible Applications in Solar Energy

ABSTRACT Solution growth technique was used to deposit thin films of Manganese Suphide (MnS), Calcium Sulphide (CaS), Magnesium Sulphide (MgS), Barium Sulphide (Bas), Zinc Fluoride (ZnFz) and Calcium Oxide (CaO) on micro-slides (Substrates) at different bath parameters which include temperature, molarity of solution, Volume of solution and water, time of d.eposition and pH. The absorbance, A was measured using spectrophotometer ranging from ultraviolet to visible regions. The Transmittance, ...

Effect of Magnetic Field on the Thermal Conductivity of Single Crystal

ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the superconducting energy gap of YBa2Cu3O7- decreases in response to increasing temperature and applied magnetic field. At a critical temperature of ...

Physico-chemical Parameter Review of Drinking Water Portability at Daranna Community, Bagudo LGA of Kebbi State, Nigeria

Drinking water quality was investigated at Daranna community the mineral rich part of Kaoje town in Kebbi state, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a physical and chemical analysis of drinking water samples was carried out for samples collected at different locations within the community areas. A number of parameters such as colour, temperature, pH, electric conductivity, dissolved oxygen, total hardness, COD, ...

Telecommunication Services and Economic Development in Mogadishu Somalia

ABSTRACT  Since destruction of Somali central government in 1991, a number of telecommunication companies have been established to provide telecommunication services in Mogadishu Somalia that there is no significant studies have been done to determine the contribution of telecommunication services on the economic development in Mogadishu Somalia. Therefore, the study was conducted to examine the relationship between telecommunication service and economic development in Mogadishu Somalia. The...

The Gateway for the people with Special needs: Connecting people to information and services through web portal

This paper describes a research project which developed a Web Portal for the peoples with disabilities or people with special needs and their family members (if any of them are disabled).In India 2.21% of total population in India has disability . In them 2.41% of male population in India is disabled and 2.01% of female population are disabled[7] according to stats of 2021A web portal has been developed as part of a research project undertaken as a part of minor project. The project objecti...

Vedas and Knowledge of our Ancestors: True origin of microbiology.

India is treasure of traditional Knowledge which has been disseminated through non-institutional means from generation to generation and is, for the most part, undocumented. However, the knowledge about microbial world by Indian Rishis presented in Sanskrit Shlokas or Suktas of our traditional manuscripts such as Vedas remained unseen. Before the invention of microscope modern science had little knowledge about the microbial biodiversity which is very clearly Presented in Vedas and Gita. ...

Potentially Toxic Elements in Food Crops Grown on Urban Waste Dump-Sites A Case Study of Wakaliga Dump-Site, Kampala City, Uganda.

ABSTRACT This study aimed at investigating the seasonal variation in the levels of contamination in soils, food crops, and domestic spring water samples from Wakaliga dumpsite in Kampala. Potentially Toxic Elements (PTE) and physicochemical properties were analysed during the dry season (May-July 2017) and the wet season (September-November 2017) and the results compared to standard limits set by international and local agencies. The results obtained indicated that some of the elements were ...

Vedic and Ancient Knowledge: Trends towards Life Sciences and medicinal microbiology.

Vedas are considered Ultimate Source of Knowledge and the most ancient written literature of the world. All great ancient thinkers and Philosophers. From Brahma down to Jaimini opine that the Vedas are as old as the advent of man and believe that the Vedas are Revelation. The natural outcome of the. Optimistic and robust outlook, which the ancient Indians had on life, was a keen desire to live a long and healthy life of a hundred years. They advocated the theory “Prevention is better tha...

Enumeration of Most Common Microbes Responsible for Tomatoes Spoilage

Abstract This study investigated the microorganisms associated with the spoilage of tomato (Lycopersicum esculentum) obtained from two markets in Jahun town, Jahun Local Government in Jigawa State, Nigeria. A total of five species of bacteria were isolated and identified viz: Bacillus subtilis, B.aureus, Escherichia coli, Klebsiella aerogenes and Staphylococcus aureus. The most prevalent bacterial isolate was Bacillus subtilis with 24% and was found in all samples from the two markets. Klebsi...

Integrated Aerogeophysical Methods for Litho-Structural Characterisation and Radiological Hazard Assessment of Parts of the Igarra Schist Belt, Southwestern Nigeria

ABSTRACT Integrated aerogeophysical datasets (aeromagnetic and airborne radiometric) were used for the litho-structural and depth characterisation and to assess the environmental radiation risks in part of Igarra, southwestern Nigeria. The total magnetic intensity (TMI) reduced to the magnetic equator gridded data were enhanced using first vertical derivative, analytic signal, tilt derivative, and spectral and Euler deconvolution analyses to improve and enhance the subsurface rocks’ textura...

Adaptive E-learning System

Adaptive learning for individual learners has recently become popular in education. This study examines Adaptive E-learning system. Meanwhile, the purpose of this study is to examine if Adaptive E-learning system caters for the needs of students to personalize learning contents or materials tailored to the individual student. To achieve this, the descriptive research method was used. This study used an Adaptive E-learning System that is Google Classroom platform for learning Microsoft Excel. ...
