This work focused on the designing of medical diagnosis system using Supervised Machine Learning. Logistics Regression Algorithms (LRA) was adopted, the label inputs for the data set which the symptoms were trained and mapped with the input of the user. Diagnosis of malaria was considered in this work; the system verified the value of the logical regression in the medical decision support system. Medical practitioners and other health workers can use this system to make better decisions in medical diagnosis for malaria. Adoption of this system will reduce stress of diagnoses malaria from patient and reduce congestion in our hospitals.

Another kind of ultra-fast phenomenon, superluminal transmission of light pulse，was proposed, its velocity can faster than the infinite that was proved in theory and experiment. Based on two kinds of epistemology and world, both deeply effects on Science and technology and open new application of Laser discussed briefly. We also suggested add the content of two kinds of epistemology and worlds in Physics to clear the relationship between the Relativity and general Physics

This study propose the use of heterogeneous visual landmarks, points and line segments, to achieve effective cooperation in indoor SLAM environments. In order to achieve un-delayed initialization required by the bearing-only observations, the well-known inverse-depth parameterization is adopted to estimate 3D points. Similarly, to estimate 3D line segments, we present a novel parameterization based on anchored Plücker coordinates, to which extensible endpoints are added

Pour Point Depressant (PPD) Testing are used extensively to modify the crystallinity of hard waxes and to reduce the natural pour point of crude. The best PPD chemical and best dosage for crude oil treatment will be chosen based on the laboratory test results to: Reduce pour point of crude oil; Reduce viscosity of crude oil; Improve rheological properties of crude oil; Reduce wax deposition rate and pipeline restart pressure. The chemical performance evaluation for PPD, proposed to use at X Oil Field has been conducted in Crude oil and Petroleum products Lab. The following properties have been determined in laboratory for blank sample (which is a mixture of H1, H4 and H5 crude oil samples with ratio of 2.1:1.4:1.0) and sample treated by PPD (rundown crude oil sample): Pour Point (for blank sample and treated sample); Wax Appearance Temperature (WAT) and Wax Disappearance Temperature (WDT) (for blank sample); Dynamic Viscosity (for blank and treated samples); Yield Stress by Rheometer (for blank and treated samples) for 100 mins, 1000 mins and 02 days shut-in times; Wax Deposition Rate by Cold Finger for blank and treated samples; Restart Pressure by Restart Loop (for blank and treated samples) for 100 mins, 1000 mins and 02 days shut-in times.

The study investigated the access and management of electronic information resources in Umaru Musa Yar’adua University Katsina, library. The study adopted quantitative approach as research paradigm; with survey as research methods. Questionnaire was used as the primary instrument for data collection in which the entire forty two library staff was used as population of the study. The response rate of 92.9% was obtained, used and analyzed the data. From the findings of the study therefore, the influence of demographic variables (gender, age, education and professions) about the management of electronic information resources was not significant at the surveyed university library. Thus, the study recommended increased investment in ICT facilities, staff training and development at the surveyed university library to promote increase in the management of electronic information resources to satisfy the needs of users as ultimate goal of any library and information center.

In one of our previous articles, we developed a cassava starch material reinforced with coconut mesocarpfibers. Its properties have been evaluated. It appears that the behavior of the composite depends on the atmospheric conditions of exposure. The purpose of this work is to do a more in-depth physicochemical stability analysis. To do this, identical samples were exposed in different chemical environments: basic, saline, acidic and distilled water. The mass losses are measured after 75 days of immersion in the different solutions in three cases: films without addition of lime and fibers, film with the presence of lime and without reinforcements, and finally the composite with lime and fibers. We observe that, in all cases, the loss of mass decreases with the addition of lime and fibers. However, in the basic solution, this decrease is greater (53.4%) while it remains acceptable in a saline environment (1.1%). In short, this material can be used for several applications in the field of packaging such as the preservation of dry salty products.

Cement Treated Base (CTB) is a pavement layer located between the sub-base and surface layers. This pavement layer uses fine aggregate (sand) and cement as a binder. Fly ash is coal burning waste that can be used as an added material for road pavement. This study aimed to analyze the use of fly ash in the cement treated base pavement mixture. Fly ash was used as a substitute of cement. The composition used consists of fine aggregate (sand), cement, fly ash and water. The compressive strength test was carried out on variations in the composition of the test object. The requirements for CTB specifications were to have compressive strength test results ranging between 45 kg/cm2 – 55 kg/cm2 at the age of the test object for 7 days. After being tested, it was found that the composition of 70% fine aggregate (sand), 5% Portland cement, and 25% fly ash had an average compressive strength of 49.823 kg/cm2.

Automatic emotion detection is a key task in human machine interaction,where emotion detection makes system more natural. In this paper, we propose an emotion detection using deep learning algorithm. The proposed algorithm uses end to end CNN. To increase computational efficiency of the deep network, we make use of trained weight parameters of the MobileNet to initialize the weight parameters of our system. To make our system independent of the input image size, we place global average pooling layer On top of the last convolution layer of it. Proposed system is validated for emotion detection using two benchmark datasets viz. Cohn–Kanade+ (CK+) and Japanese female facial expression (JAFFE). The experimental results show that the proposed method outperforms the other existing methods for emotion detection.

Productivity plays a vital role for business because it controls the real income that is needed to meet obligations to customers, employees, shareholders, and government through taxes and still remain competitive in the marketplace. An effective way to increase productivity is to eliminate waste in the manufacturing process, therefore using lean methodology. This study aims to use one of the lean tools which are value stream mapping (VMS) to identify wastes and improve the efficiency of the sachet filling process in manufacturing company. In conjunction with state mapping, re-engineering of the manufacturing setup was also developed. The future state map shows that after the streamlining process non value added time was reduce by 43.13%. Total lead time was also reduced from 118.63 hrs to 64.96 hrs and total man-hours were reduced from 189.26 hrs to 105.93 hrs which provide significant savings to the organization with respect to labor cost.
