The degree of usefulness of a document to the resolution of a decision problem is not only a function of terms in the document index matching terms in the user query. It is also a function of the user’s ability to express the problem in query terms that will facilitate document retrieval. This user’s ability is dependent on the experience as well as cognitive capacity of the user. A fuzzy logic model for capturing document degree of usefulness in the resolution of decision problem is presented in this study. The model is based on three parameters namely: (i) number of similar problems handled by the user, (ii) number of years the user had spent in the establishment and (iii) user’s direct rating of the document. The output of the fuzzy inference process is a document degree of usefulness to the resolution of decision a problem. The model has been integrated into a decision support system developed in another study which produced a platform for searching for relevant documents based on their previous usage.

The objective of this paper is to determine whether the introductory computer course in Preparatory Year Program (PYP) influences students’ performance and attitude towards computer studies in Qassim University, Saudi Arabia. The instrument employed for examining the attitude towards computer studies is Computer attitude scale (CAS) by Loyd and Gressard. A questionnaire is prepared for investigating students’ perceived computer skills. This paper is an analysis of the computer attitudes and skills of all students enrolled in PYP. Measures were taken at two points during the course: at the beginning of the course and at the end of the course. A paired sample t-test is applied using SPSS, version 21 to find the significant difference in the attitude and skills. This study concluded that in computer knowledge, and in promoting positive attitudes towards computer skills, the PYP program achieves significant increases in these areas. The course proved to effectively improve students’ attitude and skills.

DOI: 10.9734/BJMCS/2016/24498

In this note, we model various types of graphs, relational systems and multisets as coalgebras over Set×Set and use the theory of coalgebras over arbitrary categories to conclude properties of the category of graphs. This point of view forces the formulation of a Co-Birkhoff like theorem for graphs.

An Elementary Proof of Riemann’s Hypothesis by the Modified Chi-square Function

DOI: 10.9734/BJMCS/2016/25419

Riemann’s hypothesis has always been a challenge in number theory, thus the present article shows a general (i.e. valid for any non-trivial zero) and elementary (i.e. not using the theory of complex functions) proof of it, in which the constant +1/2 arises by itself and automatically. In addition the method gives the values of all the trivial zeroes of Riemann’s function. The following steps are used: The modified chi-square function with its parameters Ω, k and ω=ω(k), in one of its four forms (±1∙/)Χk2(Ω,x/ω), as the interpolating function of the {nα} progressions and of the sums {∑nα} with α∈R so that k=2±2α for α<0 and α>0 respectively; the Euler-MacLaurin formula; the shift real vector operator Σ≡ (Σα Σk)≡ (Δα Δk)≡ (+1 (4α–2)) in the Euclidean 2D space (α k) and its extrusion to the imaginary axis it, leading to the 3D shift complex vector operator Σ≡(Σσ Σk Σit)≡(Δσ Δk iΔt)≡(+1 (4σ–2)  it) with norm Σ2=16σ2–16σ+5+t2. The condition Σ=0 that is │Σ│=Σ=0 leads to prove RH.

Mining Approximate Functional Dependencies (AFDs) from a database may produce valuable interesting relationships among its variables that would be beneficial in several domain applications such as marketing, financial data analysis, biological data analysis, and intrusion detection. Mining of association rules is concerned with extracting new knowledge from databases in the form of patterns and associations among data items. The mining of AFDs still posing special set of challenges such as the space and time requirements in addition to the quality of the discovered AFDs. In this paper, an approach for AFDs mining is being developed through employing the specificity interestingness measure and its monotonic property used in some association rules mining algorithms. This approach has been tested on a set of test bed of datasets. The results showed an improvement in time requirements and in the number of mined AFDs.

DOI: 10.9734/BJMCS/2016/24854

The dawn of Internet of Things (IoT) has started its journey for new era of smart and portable devices. IoT is regarded as hard-core for integrating various sensors, microcontrollers and all sorts of communication protocols and lays the foundation for futuristic communication standard i.e. Human-Things Interaction. The aim of this research paper is to highlight the concept of Internet of Things (IoT) and in addition to this, a Data Glove- An IoT based smart wearable gadget capable to perform various tasks like temperature monitoring, ambient light detection and gesture control has been proposed. Data Glove is equipped with various sensors like LM35, Ambient, 3-Axis Accelerometer and Arduino IDE Serial Monitor for capturing the sensor data. Data Glove is highly energy efficient and can be operated by 9V battery and has huge potential for live implementations in varied areas like Robotics cum Artificial Intelligence, Corporate Houses for Sensor data measurement, R&D Institutes and even can be deployed in various day to day activities.

The healthcare sector today are looking for opportunities to improve their daily operations efficiencies, increase pharmacist and pharmacy technician efficiency and  improves patient care by promoting medication dispensing accuracy and allowing pharmacists to spend more time on patient care activities. The aim of this work is to design and model an Integrative computerized pharmacy inventory system that would have the capability to improve patient care by promoting medication dispensing accuracy and also allow pharmacists to spend more time on patient care activities, using University of Calabar Teaching Hospital (UCTH) pharmacy as a case study. The specific objective of the system is to provide better security by more securely controlling access to medications in the pharmacy, Saves space – reduces pharmacy storage footprint, aids in Joint Commission compliance by providing complete audit trail of all transactions. In this paper we adopted the structured system analysis and design methodology (SSADM). UML (Unified Modeling Language) is used for the model design. The interface between the front-end and the back-end is through SQL (in WAMPSERVER) and through an application program interface (API) defined in PHP. PHP is used as back-end for managing access structures, query evaluation and optimization, concurrency control and recovery. NetBeans IDE was used as front-end to develop forms, report-trail, and graphical user interface.
