Textured Contact Lens IRIS Detection Methods: Review[ ]


A person's biometric traits can be used to identify them in a variety of ways. One of these characteristics is IRIS detection systems. Iris recognition systems in use today are susceptible to iris presentation attacks. Among the several iris presentation attacks, textured contact lenses are possibly the most difficult to detect. In the last five years, no specific survey focusing on IRIS detection, specifically Contact Lenses Iris Detection Algorithms (CLIDs), has been published.

Heart Disease Prediction System using Electrocardiogram[ ]


Heart disease is a major problem in the society. Among numerous deadly diseases, heart disease has gathered much attention in medical research. According to WHO (World Health Organization), millions of people die due to different heart diseases every year. Predictions of heart infirmity is considered as one of the key matter in clinical information analysis. Its diagnosis is very challenging because of its complexity and if the disease is falsely predicted, the treatment provides no cure. The prediction of cardiovascular illness is commonly formed on signs, symptoms and physical check-up of the patient.

Agree to Act Together: An Exposition of the Contemporary Laws on Conspiracy Under Ghanaian Criminal Jurisprudence[ ]


Conspiracy, as one of the four main inchoate criminal offences, has not only been effectively safeguarded and ingrained in Ghanaian Criminal Jurisprudence, but requires a careful consideration in its formulation under statute in order not to superfluously exonerate offenders from being culpable. This paper aims to discuss the current essential elements of conspiracy, the liability or otherwise and punishment of a conspirator(s), and argues strappingly that the Ghanaian Courts have now shifted from a restrictive evidential approach adopted immediately after the coming into force of the new rendition to a broad evidential approach which in effect have reduced the unbearable burden on the prosecution and strictly hold offenders accountable.

The Design of Fluid Holding Tank Control System Using Programmable Logic Controller (PLC)[ ]


In the midst of technological advancements, there are a number of industries in Liberia that uses primitive techniques in controlling the daily operation of fluid storage tanks. These industries such as the Liberia Petroleum Refinery Corporation (LPRC), etc, still use the rudimentary methods of allowing personnel to carry on the daily operations of storage tanks during productions, which place the personnel involved into hazardous situation and also lead to inefficient productivity. However, to avoid workers physical interaction with these holding tanks that pose danger to their lives, industries operating in Liberia, need to employ an automatic control system that carries out the daily opera-tions of these tanks without workers physical interaction with them. This laborious and risky task can be performed using automatic control system that both monitors the fluid level in the tanks during pumping and stops the pump when the desired fluid level has been achieved.

NUMIRICAL MODELING OF CIRCULAR POCKET CONNECTIONS WITH ROUGH AND SMOOTH SURFACE INTERFACE USING FINITE ELEMENT METHOD[ ]


Although pocket connections are used since the 1950’s, there are only a few researches addressing the behavior and design of this connection, especially for circular columns. Generally, there are two types of pocket connections, internally and externally embedded connection. These configurations limit the use of such connections in the case of bridges, where big moments need to be transferred to the footing. Hence, an extensive experimental program was conducted at Ain shams University-Cairo, to study the behavior of pocket connections. A new pocket configuration with partially embedment is introduced in these studies.

CRITICAL APPRIASAL OF TWO RESEARCH DONE ON CHOLERA OUTBREAK RESPONSE[ ]


In as much as early investigations of cholera have moved toward becoming models for present day study of disease transmission , foreseeing and controlling outbreaks of cholera is as yet a noteworthy test in the developing regions of the world. Upgrades in the sanitation level and the utilization of rehydration treatment done orally has incredibly lessened the burden of cholera, yet there is no prescient system to predict disease outbreaks and getting ready for interventions. Numerical demonstration is one way to deal with combining our insight into cholera as a quantitative system.

CONCEPT OF PHYSICAL HYGIENE IN CLASSICAL YOGA[ ]


Preservation of good health is important. For this we must follow certain rules. We must observe the laws of health and certain golden rules for life. The most important rule of life is obviously “Hygiene”. Health and hygiene are inseparably connected. There can’t be good health if we live in unhygienic condition and keep our body unhygienic. As per the world healthorganisation (WHO) hygiene means: “Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases”.We must have a clear idea of what diseases are and how it is caused. We can very well avert diseases if we understand the biological laws which govern life, the rules of health and hygiene and the importance of cleanliness.

Improving the Stability and Durability of Cement Stabilized Earth Blocks Using Local Additives for Quality Low-Cost Houses in Developing Countries[ ]


The earth material(mud) used for building construction naturally possesses an inherent non-toxic qualities that ensures good in-room quality houses for the occupants. However this wonderful material is also naturally weak to water penetration/erosion and low in compressive strength if unstabilized. This makes it unfit in its natural form for modern housing requirements. To overcome this inherent weakness of the earth material, traditional earth builders usually apply several measures including choice of soil types and use of natural additives to stabilize the material for housing purposes.
