Long-term isothermal stability of deep eutectic solvents based on choline chloride with malonic or lactic or tartaric acid[ ]


The increasing amount of papers published on ionic liquids generates an extensive quantity of data. Deep eutectic solvents (DESs) have recently been developed as a new and attractive alternative to traditional ionic liquids. The thermal stability of a deep eutectic solvent is an important parameter and limits the maximum operating temperature. The long-term thermogravimetric studies of DESs such as malonic, lactic and tartaric acid with choline chloride showed non-linear weight loss as a function of time at each temperature of 20 °C interval in the range 60-120 °C over a period of 10 hours.

Framework for Secured Biometric System[ ]


Biometrics provides higher accuracy of personal recognition in real identity management system than traditional methods because of its properties. However, the security of biometric systems can be undermined, if the template derived from the biometrics traits such as fingerprint is compromised. If a biometric template is compromised, it leads to serious security and privacy threats. Unlike passwords, it is impossible for a legitimate user to revoke his/her biometric traits and switch to another set of uncompromised identifiers.

Experimental Determination of Water Content of Sweet Natural Gas with Methane Component Below 70%[ ]


Majority of the experimental data for water content of natural gas had always been based on gas composition with methane component greater than 70%. However, some low pressure natural gases can have a methane component less than 70%. This study therefore, was on measuring the water dew point of sweet natural gas with methane component less than 70 %. To achieve this, natural gas samples were collected from several oil and gas locations in the Niger Delta region, in accordance with ISO 10715. An experimental set up was designed for use with a chilled mirror dew point meter. On performing the experiment, the water dew points were measured and the water contents estimated using appropriate correlations, attached to the dew point meter. The water contents were then validated with a modified version of the Soave Redlich Kwong (SRK) equation of state and the Peng Robinson equation of state suite of the proMax software. The result showed a maximum percentage average absolute deviation (% AAD) and standard deviation (SD) of 11 and 12 respectively. It was also observed that the measured dew point temperatures and water contents of the gas samples in this study were relatively the same, at same pressure, with those with methane component greater than 70%.

LOCAL CONTENT BASED INTELLIGENT TRAFFIC CONTROL SYSTEM FOR SMART CITY[ ]


Traffic congestion at intersections is commonly noticed whenever there is heavy traffic flow towards the intersection and usually results to delay which causes time wastage, fuel wastage and minor accident in some cases due to the violation of ‘right of way’ rules. Most of the available intelligent traffic systems are expensive for implementation and maintenance in this part of the world (Nigeria/ Africa as a whole). Several of the traffic control lights in Nigeria are mostly pre-timed (that is, they cannot respond to the dynamic nature of traffic). In view of these, low cost, local-based intelligent traffic lights control that suit Nigeria/Africa state of weather and environmental condition was designed and implemented for a particular situation (University of Ibadan Main entrance gate).

Food Insecurity is a global issue especially for developing countries like Pakistan that has been facing this major problem. Many reasons exist behind food insecurity in Pakistan such as, supply of bad quality food, smoky environment etc. Research objective is to find the factors which are responsible for the problem of food insecurity and undernourishment in Pakistan with main focus on food inflation. Furthermore, this study identifies the factors which are responsible for growing the food insecurity in the country under. Food insecurity is measured from depth of food deficit (kilocalories per day) that indicates how many calories would be needed to elevate the undernourished from their category. Secondary data is taken from WDI etc. Co2 Emissions, Law & order, Unemployment rate, Urban Population, food inflation, Prevalence of undernourished used as independent variables whereas, food deficit and food insecurity are used as dependent variables. Simple regression modal is applied for analysis. In result, Total Population, Co2 Emission, Food Inflation, Risk of Law & Order, Unemployment rate and Prevalence of Undernourished are positively related with dependent variable whereas, Urban Population negatively affected with dependent variable. Government should pay attention on implementation of effective policies, giving awareness about factors which are mainly cause the food insecurity.

Information based feature selection for intrusion detection systems[ ]


Intrusion detection is the act of detecting harm full attacks towards computer systems and networks. Intrusion detection systems are used to identify and report those intrusions in order to take necessary remedial actions. We use can use real time network data collected from various sensors or devices for analyzing the traffic. Also there are various standardized data sets which contain various types of intrusions such as DARPA and KDD Cup99 data sets. We use NSL-KDD dataset for our analysis as NSL-KDD is an improved version of KDD Cup99 data set. Here, we evaluate the intrusion detection system by with and without applying data pre-processing and feature selection techniques. Thus we analyze the importance of data pre-processing and feature selection applied on the data set using rough sets and information gain.

Elliptic model for the consideration of the anisotropy by the fatigue criteria: application to wood material[ ]


Wood is a material widely used in construction. The determination of its properties is very difficult because of its anisotropy. A presentation of both the physical and mechanical properties of wood has been made in order to understand and further explain the mechanisms responsible for its anisotropy. The modeling of the anisotropy has been done at the level of the stress limits. We assume that they form an ellipse call the anisotropy ellipse, for anisotropic materials and a circle for isotropic materials. The fatigue limit which appears in the expression of the Fogue-Bahuaud criterion was replaced by the equation of the ellipse obtained. A comparison with the literature results and an application on two species of tropical timber, the Azobe and Bilinga, were used to validate the results.
