Image and video content analysis applications typically require functionalities such as object classification, detection and tracking, and activity recognition. Objects may undergo translation, rotation, and changes in scale due to perspective projection. Further, the appearance of objects and illumination conditions may change over time. Occasionally objects might also occlude one another in the scene making consistent classification, detection, and tracking a challenge. To reduce the effect of these limitations it is proposed to model objects in wavelets domain using silhouettes. The silhouette of an object is characterized using projected histograms of sixteen wavelet primitives extracted from a silhouette map of the scene. A classifier based on eigen decomposition of histogram of feature vectors combined with sparse coding prediction is presented. The model of a class is represented as over complete dictionary of sparse codes. For robustness multiple classifiers based on the same sparse code operate in parallel but at different scales. It is combined with spatial histogram classifier to realize a bank of multiple classifiers. The accuracy of the proposed classifier is compared with support vector machine and published state-of the-art results. Accuracy evaluation and real-time performance demonstrates competitive performance with the published stat-of-the-art results. © 2014 IEEE.

Literature shows that power generation capacity in sub-Sahara Africa is lower than that of any other region in the world and capacity growth has also stagnated. Africa currently faces major electricity shortages with a number of power outages which has the tendency of rendering many firms less efficient in their production. This study therefore seeks to find the impact of power outages on production efficiency of firms in Africa. The source of data is the World Business Environment Survey conducted by the World Bank. The analysis deployed stochastic production frontier and a two-tail Tobit models. The finding shows that the number of power outages experienced in a typical month has a negative impact on the production efficiency of firms in Africa. This call for immense investment projects in new generation capacity in order to ameliorate the negative effect of power crisis on production process of firms in Africa. © 2016, Econjournals.

Food labelling is an important communication tool between consumers and food manufactures. Consumers' ability to read and understand information on a food label is vital. This study was aimed at determining the relevance of food label information to consumers in the Kumasi metropolis of Ghana. Structured questionnaires were administered to 455 respondents who were randomly selected from retail centres in Adum, Kumasi. Respondents buying indicators were in the order of expiry data, nutritional information, ingredients, taste and appearance with product price being the least. Respondents were generally conscious of date markings. Food related diseases of most concern to respondents were Diabetes (35.60%) and Hypertension (25.1%). About 45% of respondents were concerned with colour additives in food. Whiles about 89% of respondents had ever read storage instructions, 84.8% actually followed the storage instructions. Conclusively, respondents were fairly knowledgeable in the use of food label information. © 2012 Elsevier Ltd.

Compaction of blocks contributes significantly to the strength properties of compressed earth blocks. This paper investigates the influence of compacting rates on the properties of compressed earth blocks. Experiments were conducted to determine the density, compressive strength, splitting tensile strength, and erosion properties of compressed earth blocks produced with different rates of compacting speed. The study concludes that although the low rate of compaction achieved slightly better performance characteristics, there is no statistically significant difference between the soil blocks produced with low compacting rate and high compacting rate. The study demonstrates that there is not much influence on the properties of compressed earth blocks produced with low and high compacting rates. It was further found that there are strong linear correlations between the compressive strength test and density, and density and the erosion. However, a weak linear correlation was found between tensile strength and compressive strength, and tensile strength and density. © 2016 Humphrey Danso.

Objective: The study surveyed child safety restraints use among drivers transporting children to school in Dansoman, Accra. Method: Employing a naturalistic observational method, the following were observed: sex of the driver, vehicle model, child characteristics, child location in the vehicle, whether child was restrained and how they were restrained, whether the driver was belted and the presence of other vehicle occupants. In total 126 vehicles were observed. Results: The study revealed low child restraints use among the observed drivers; children in new vehicles were more likely to be restrained; children seated in the back seat were more likely to be unrestrained; and child occupants were more likely to be unrestrained where there were other vehicle occupants. Conclusion: The study maintained that a collaborated effort by road safety stakeholders in terms of education/awareness creation and subsequent strict enforcement of child restraints use laws were required. © 2014 Elsevier Ltd.

This research was conducted in the Akantansu stream of Tutuka in Kenyasi in the Brong Ahafo Region of Ghana in the months of October and November 2010 and January 2011. The major objectives of the study were to measure levels of pH, BOD (biochemical oxygen demand), lead, chromium, and arsenic in the Akantansu stream of Tutuka and to find ways that the community could ensure safe water use. To achieve the objectives of the study, sampling was done over a period of three months and data was collected and analyzed into graphs and ANOVA tables. The research revealed that the levels of arsenic and BOD were high as compared to the standards of WHO and EPA. If the people of Tutuka continue to use the stream, they may experience negative health effects (e.g., nausea, vomiting, diarrhea, etc.). The level of pH, chromium and lead was acceptable as compared to the standard of WHO and EPA. Copyright © 2013 by ASME.

The Brunauer, Emmett and Teller (BET) method for estimating specific surface areas of adsorbents that is widely applied in food science and engineering operations has been shown to be expressed in wrong dimensional units and this explains the wide discrepancy, of several orders of magnitude, often observed between specific water and N 2 surface areas of adsorbents when using the BET method. A method based on Caurie's unimolecular adsorption theory predicts the specific water and N 2 surface areas in the same units and in their correct order of magnitude which for cornstarch equals, respectively, 258.88 and 169.86 m 2 g -1 compared to BET estimates of 283.60 m 2 g -1 for water and only 0.73 m 2 g -1 for N 2. © 2012 The Author.

Sixty eight personnel in the food service in Kumasi in the Ashanti Region, Ghana, with varied educational and job experiences were given training on basic food hygiene. Personnel were divided into 4 groups and each group given 8 hours full day training. Topics for training were broadly on 'Food Hygiene', 'Personal Hygiene', 'An Introduction to National and International Food Legislation and how it affects the food handler', and 'Fitness at work based on International Food Standards'. Most participants had an average awareness in food hygiene; this included an appreciation of what could be considered food hazards, whether food hazards are preventable, those in charge of ensuring food safety, and why food handlers need to keep their food safe for their customers. The standard examination consisted of questions like differences between 'use by' and 'best before' dates, the temperature range considered as the danger zone, the appropriate storage temperatures for storing long and short shelf-life products in the freezer, chilling temperatures and how to handle high risk products.

It has been pointed out that the Clausius-Clapeyron equation which is currently used to measure isosteric heat of adsorption in reality measures the latent heat of evaporation. The usual Clausius-Clapeyron plot that decays rapidly to low values at low Aws has been compared with a suggested alternative equation derived directly from an expanded form of Caurie's unimolecular adsorption equation. The plot of the proposed equation is higher than that of the Clausius-Clapeyron equation, and it has the shape of an inverse sigmoid isotherm. Two discontinuities in the proposed plots are stated to demarcate three energy levels corresponding to three states of bound water recognised to exist along sigmoid food isotherm plots. © 2012 Institute of Food Science and Technology.

Parameters of Caurie's [International Journal of Food Science and Technology40 (2005) 283] unimolecular adsorption equation have been used to calculate total bound water to equal the square of the primary water capacity or m02 grams. Current freezing methods predict bound water up to nm0grams which leaves a fraction of the total bound water with limited freezing properties unaccounted for. From these studies three types of bound water have been identified at room temperature along a decreasing energy gradient. It has been shown that the stability of processed and blended foods will improve with formula modifications consistent with expansion of type II bound water molecules and processed foods will be more stable the smaller the fractional ratio of type III to type II bound water molecules. © 2011 The Author.
