  • Predicting Traffic Congestion Time Based on Kalman Filter Algorithm

    This paper mainly solved the problem of predicting the time required for vehicles to pass through congested roads. In order to obtain more accurate prediction time, a Kalman prediction model based on multiple linear regression was established in this paper. Taking the 2008 Yanan elevated road in Shanghai as an example, the measured data in this section was collected from the traffic measured data sharing network, and the above model was used to obtain good prediction results. As an improvement, we used BP neural network instead of multiple linear regression to make the prediction result more in line with the actual situation.

  • Assessment of Football Cooperation Performance Based on Evaluation Model: a Case Study of the Everton Team

    To comprehensively measure the effect of football team cooperation, this paper established a football team performance evaluation model and takes the performance of Everton F.C. in 2017 to 2018 season as an example. We selected 12 indicators from three aspects and use hierarchical clustering to divide the performance into four levels: very successful, relatively successful, unsuccessful and very failed. Then, we evaluated the performance of the team’s changes and focus on the opponent’s strategy indicators to analyze its impact. It is found that the reason for most of the failed games is that the team is affected by the away effect, the intra-team cooperation is not dominant and the opponent’s ability is strong, resulting in low CPI scores. At the end of the season, the influence of the opponent strategy on team performance becomes stronger and stronger.


    The objective of the present study was to investigate the performance, haematology and serum biochemical parameters of rabbits fed different levels of fermented Lagenaria brevlifora extract (LBE). A total of fifty (50) weaner rabbits aged 9-10 weeks with an aver-age weight of 405 ± 1.8 were allotted to five treatments with 5 replicates of two rabbit per replicate in a CRD. Treatment 1 was fed 0 ml LBE while 2, 3, 4 and 5 were fed LBE at 20ml, 40ml, 60ml and 80 ml per liter of water respectively and the experiment lasted for 12 weeks. The data obtained was used to evaluate the growth, haematological parameters (PCV, RBC, Hb, MCV, MCH , MCHC, WBC and its differentials ), serum biochemical indi-ces (Albumin, globulin, total protein, urea, creatinine, cholesterol, calcium, phosphorus, ALP, AST and ALT). Result obtained revealed that there was a significant differences (P


    The objective of the present study was to investigate the performance, haemato-biochemical parameters of broiler chicks administered Daniellia oliveri leaf extract (DOE) as an antibi-otic alternative. A total of 250 (Ross 308) one-day old broiler chicks were allotted to five treatments in a completely randomized design and each treatment group was further sub-divided into five replicates containing ten (10) birds each. Treatment 1 (Control) was given 1.20 g/ liter of Neomycin in water, while treatments 2, 3, 4 and 5 were given DOE at 10 ml, 20 ml, 30 ml and 40 ml/liter of water respectively. The experiment lasted for 8 weeks dur-ing which performance, hematology and serum parameters were recorded. Average daily gain (DWG) and feed conversion efficiency (FCE) were significantly influenced by the die-tary treatment (P0.05). However, increasing the level of DOE from 10 ml to 40 ml/liter tend to decrease the AFI. Highest mortality was recorded in birds fed T1 (10%) followed by T2 (3%), T3 (1%) respectively, none was recorded in T4 and T5. Results on hematology revealed that there were significant differences (P

  • Village Chicken Breeding Objectives and Trait Preferences of Chicken Producers

    This study was carried out to generate baseline information on village chicken production objective, breeding practice and trait preference of chicken producers in South Achefre, Banija and FagitaLekoma districts of western Amhara. Multi-stage sampling procedures were employed to select the study villages and respondents, where nine villages and 180 respondents were selected by purposive and random sampling techniques, respectively. Data were collected by individual survey using Open Data Kit. The collected data were analyzed using descriptive statistics of SPSS version 20 and ranking index. The main purposes of keeping chicken in the study area are the sale of egg and live adult chicken and farmers have a multiple breeding practice. The exotic breed was the first priority of chicken producers. The three most preferred traits for the selection of breeding hen are egg production trait, disease resistance and mothering ability, while the three most preferred traits for the selection of breeding cock are body conformation/ physical appearance, body size and disease resistance. Comprehensible knowledge on breeding practices, objectives and trait preferences of chicken owners are crucial for the development of holistic and applicable genetic improvement programs. Hence, production objectives and trait preference should incorporate in designing genetic improvement breeding programs to assure sustainable utilization and improvement of indigenous chickens.


    Homegardens (HGs) in South West Ethiopia are well known practices playing an important role in both biodiversity preservation and socioeconomic aspects. However, increased human population in line with scarcity of land for food production and expansion of cash crops in the area have been exerting pressures on its component diversities of which horticultural crops are the major. The aim of this study was to examine trends of horticultural crops production based on local’s point of view and measure currently existing plant diversity in HG (HG) by means of multistage sampling from a total of 133 households and 15 key informants using a semi-structured questionnaire with 9 FGD discussions. Descriptive statistics and multiple linear regressions and measures of diversity indices were used to analyze and interpret the data. The results revealed that the socioeconomic variables had significant effects on farmer’s perception of horticultural crops production trends (58% variance explained). Majority of the respondents agreed that recently progression in horticultural crops production linked with more to the increments in horticultural crops market efficiency. The study also revealed that total of 79 identified plant species that were grouped as herbs (42%) followed by trees (28%), shrubs (24%), and climber (6%). Ecological diversity indices indicated that the existing plant species in the (HGs) of the study area have moderately high biodiversity and species richness.


    Traditional pasta is made from durum wheat flour and water and is a popular food product in worldwide. This review tries to examine the influence of bran particle size on the quality of pasta. As part of this review desire to become healthier and eat more healthy food, regular durum wheat pasta has received competition from pasta made of whole grain flour or pasta that has been enriched with dietary fiber. Bran is the outer layer of the wheat kernel and is removed along with the germ during the milling of wheat. The bran is seen as a by-product of the milling process and is often used in animal feed. In whole grain flour, the bran is not removed but is milled and then passed back to the ground wheat flour. Wheat bran is rich in dietary fiber and antioxidants and a diet rich in wheat bran is associated with reduced risk of common health diseases such as type 2 diabetes and heart diseases. Ethiopian should increase their intake of whole grain food products since their average intake today is lower than the recommendations made by Livsmedelsverket. Despite the positive effects of wheat bran, many consumers prefer to eat foods such as pasta that is made from refined wheat flour because they tend to prefer the quality in taste and texture of these products. Knowledge on why the quality of whole grain food products like pasta become less attractive is therefore of value in order to identify new ideas on how to create and develop improved whole-grain products that are more attractive to the consumers. The particle size of wheat bran influenced surface texture of the pasta. The larger the particles that were added, the more the roughness on the surface of the pasta increased. Also stickiness of pasta was…
