  • Fuzzy Logic Control in Air Temperature and Skin Temperature in the Infant Incubator

Premature birth is a worldwide problem.
Thermoregulation is a major problem in
premature infants. A novel control
implementation of temperature control presented
in this paper. The paper overview a model design
of heat exchange between the newborn and its
environment and a robust fuzzy control algorithm.
The purpose of implementation is to improve the
operation of controlling temperature inside
incubator, two sensors required to control the
incubator air temperature and skin temperature
simultaneously. Fuzzy logic is used to
incorporates incubator air temperature and skin
temperature to control the heating. Simulation
results prove that the design provides high level
of output accuracy for a high dynamic input
range

  • Comparative analysis of chemical composition and in vitro digestibility of Bt versus non-Bt cotton crop residues in Gezira State, Sudan

Abstract: The objective of the experiment was to investigate - and qualify chemical composition of both Bt and non-Bt cotton crop residues (CCR). The in vitro digestibility of each type of CCR was also determined. Week zero represents the period before introduction of animal to graze on Bt-CCR. From each square meter of 14 square meter cotton residues were cut at 10 cm above the ground level. The components of the crop residues in each square meter were separated in to leaves, bolls and tender branches and then weighed freshly and again after drying in an oven at 105°C for 24hours. The results revealed significant differences in chemical composition of whole residues, in vitro digestibility of dry matter and in vitro digestibility of protein in Bt CCR. Crude protein and ash were higher in all components of Bt CCR and crude fiber was higher in bolls only. The in vitro digestibility showed lower levels in Bt CCR than in non-Bt CCR.

  • Fault Tolerance Temperature in the Infant Incubator Using Fuzzy Logic

Temperature is important parameter needs to be controlled in any infant incubator design. This paper improved a multisensory system to provide high level of accuracy and assurance. Four temperature sensors used to adjust the incubator temperature. The proposed system isnot only concern with the air temperature control but it also extended to monitor the skin temperature. The results prove the ability of using multisensory system with advance control such as fuzzy control to provide a smooth operation

  • Keystroke Dynamics Biometric for Securing PINs and Passwords

This paper studies the use of the keystroke dynamics biometric as
an added security for passwords and PI Ns (Personal Identification
Numbers) used in POS (Points of Sale) and banking Automatic
Teller Machines (ATM).
The paper employs an algorithm using the keystroke dynamics
which attempts to minimize compromising the security when the
imposter get hold of both user-ID (user card) and password.
Experiments were conducted using PINs (passwords) of varying
length by a group of users.
The paper reports the results of the experiments and recommends an
optimum number of digits in PINs (passwords) when keystroke
technique (this biometric) is used.
The experimental results were encouraging for PINs of length 3-6
digits where the rate of rejection of legitimate users (False Reject
Rate (FRR)) was zero while the rate of acceptance of the imposter
False Accept Rate ((FAR) ) was reduced to 24.23%.

  • Object Oriented Model Development for Education Institutes' Internal Auditing Process

The technology plays an essential role and help the organizations to work better and maximizing their operation achievements. The IT auditor plays an increasingly important role in helping organizations to manage and respond to risks. The aim of this paper is to gather some of the internal auditor’s skills to be available for other auditors in education institute and collect the experiences of the auditors to design a system and also help internal auditors to manage their tasks in a systematic way by automating the accounting files. The proposed system will help the internal auditor to take good, fast, and more accurate decisions and to provide an internal auditing system for education institute. The study used the object-oriented models to design the internal auditing system.
