One of the important network security measures on a campus network is the use of authentication for identification of legitimate users and one of the most widely used solution in network authentication is the RADIUS protocol. However, there are potential security vulnerabilities in the RADIUS network especially for networks using captive Galley Proof server in a captive portal environment which is 1000 ms [1]. After improving the OTP technique by integrating all the variants of OTP with the RADIUS server on a single server using the simulated ABU campus network using GNS3, the result shows a significant improvement over the above results. The results obtained shows the average response time for TOTP, CROTP and HOTP as 1.3s, 2s and 1.9s. The validation, based on the developed and simulated configuration was carried out using live servers, routers and switches and the results showed improvement over the above results the average response time for TOTP, CROTP and HOTP were obtained as 0.4s, 0.9s and 0.9s respectively. This shows significant improvement in the TOTP, CROPT and HOTP respectively. The result shows the average response time is less than the recommended 1000ms for RADIUS server response time in a captive portal environment.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":"19 1","pages":"1-37"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47453930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was done in order to ascertain which of the frequency ranges has the highest dielectric constant and least loss factor. The graphs of dielectric constant and loss factor were plotted against the frequency. The results were also used to plot Cole-Cole diagrams. The results revealed that the dielectric constant of methanol is higher at frequency 0.05 GHz and decrease as both frequency and temperature increases. However, as the frequency increases beyond 1.0 GHz the dielectric constant increase as the temperature increases. The results also showed that methanol actually formed a semi-circle which suggested that the solvent indeed exhibits Debye relaxation model. There were some discrepancies observed in the Cole-Cole plots which may just be attributed to the distribution of the relaxation times in the methanol. The researchers conclude that dielectric constant of methanol is higher in megahertz than those in gigahertz. The loss factor on the other hand was small at lower frequencies but as the frequency increases the loss factor also increases to a maximum value. The loss factor however decreased when the frequency increases after attaining its maximum.","PeriodicalId":91221,"journal":{"name":"British journal of applied science & technology","volume":" ","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47403791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weeds are the major biological constrain in DSR and its management contributes a major share in cost of production, as crop and weed emerge simultaneously and exerts competition right from the beginning of the crop. Field experiments were conducted in rabi 2013 and 2014 to study the effect of new herbicide combination, bispyribac sodium + metamifop 14% SE on weed control in DSR and their residual effect on succeeding greengram. Results revealed that the post-emergence (POE) application of herbicide combination, bispyribac sodium + metamifop 14% SE at 70 g ha -1 with wetter recorded significantly lower total weed density (25.78 and 24.19 plants m -2 respectively, during 2013 and 2014), total weed biomass (24.89 g m -2 and 34.56 g m -2 respectively, during 2013 and 2014) and higher weed control efficiency 1-14, (80.07 and 81.68% respectively, during 2013 and 2014). Application of bispyribac sodium + metamifop 14% SE at 70 g ha -1 along with wetter (100 mL ha -1 ) recorded higher grain yield of 5676 and 6388 kg ha -1 respectively, during both the years. Weedy check recorded the lower grain yield and recorded the higher weed index of 51.83 and 52.85% respectively, during both the years.

ArcGIS 10.0, in complimentary with Google Earth Pro and Suffer 10 were integrated with remotely sensed data such as SRTM Digital Elevation Models data, satellite imageries in conjunction with secondary data such as topographical and thematic map to analyze the terrain of kachia LGA. Relevant existing data were also acquired and processed to generate DEM, slope, contours, 3D-view and flow accumulations which were used for general reconnaissance and the analysis of the terrain, that is, the topography, landuse and landcover, drainage and some cultural features such as roads and settlements of the LGA. Viewshed analysis, Lines of Sight and 3D view were used to model the best avenue of approach by the military into the LGA. Moreover, the most suitable site for “release point” during military advance which were based on some criteria were also modeled and determined using geospatial techniques. Other military operations such as axis of advance and obstacle crossing were all demonstrated, while the scenario of the real battle ground were modeled and analyzed. The study revealed that only four Original Research Article Isaac et al.; BJAST, 19(6): 1-18, 2017; Article no.BJAST.29669 2 out of the ten routes into Kachia LGA are suitable for advance, while the best release point was found to be located in the southern part of Kaja settlement with area coverage of 18.09km 2 . Bonds such as villages like Atara, Akwana, Ungwan Kanrara, Bika and Adage as well as Rivers Katera, Awon and Bika which all lie along the axis of advance between the Release Point and Kachia were also detected geospatially as the Report Lines. Rivers Atara, Akwana and Bika were discovered to be possible obstacles along the axis of advance.
