Analysis of the effect of dual injection on combustion characteristics of Gasoline Direct Injection (Gdi) Engine

The production of hydrocarbons (HC), carbon dioxides (CO2) and nitrogen oxides (NOX) are the serious issues of Gasoline Direct Injection (GDI) during stratified lean operation. In attempt to solve these setbacks, this research explores the effect of dual direct injection on air-fuel mixture characteristics, combustion and species transport characteristics after combustion at both early and late fuel injection modes. The researcher used the 2021 ANSYS design modeler for geometry designs and meshing and used the ANSYS Fluent for simulation and numerical analysis. The results revealed that during mixture preparation phase dual injection at early injection results in higher TKE, velocity magnitude, turbulent intensity, dissipation rate but lower turbulent viscosity than when the fuel was injected late. The combustion and species transport results also revealed that at late injection, specific heat capacity (Cp) and its equivalent flame temperature was high enough to initiate dissociation of combustion products into O2, N2, HC and CO as compared to when the fuel was injected early. The turbulent burning velocity of the flame was 2290m/s at late injection while that during the early injection mode was 397m/s. Post combustion mass fraction results showed the presence of O2 and N2 in the combustion chamber in the late injection as against zero O2 and N2 in the early injection mode. Mass fractions of NOX and CO2 production were also high during late injection than in the early injection. The mass fraction of H2O vapour produced in the early injection was higher than that of the late injection mode. The study reveals that dual direct injection engine operated at early injection mode is more efficient in mixture preparation and dissipation, engine cooling effect and reduced exhaust NOX and CO2. It is therefore recommended that automotive companies in Ghana should consider the efficiency of dual direct GDI engine for emission control and fuel economy for incorporation into the Ghana-made vehicles to support Ghana’s industrialization drive.

An analysis of the use of grice’s cooperative principle in the day show

This study seeks to analyze the use of Grice’s cooperative principle and its maxims in The Day show, a television talk show on TV3. Seven different videos, representing seven episodes with distinctive themes were purposively selected based on their level of interactivity. The selected videos represented a theme on religion, social issue, personal story, education, Business, entertainment and health. The findings revealed instances of observance of all the maxims (quantity, quality, relation and manner) and occurrences of five kinds of non-observance (flouting, violation, infringement suspension, opting out). The maxim of manner emerged as the most observed maxim with 113(113%) occurrences, followed by the maxim of quantity92(36.50%), relation35(13.88%), and quality(4.76%). Regarding non observance, violating maxims had the highest number of occurrences with a total of 107(67.7) instances. This is followed by flouting25(15.8%), infringement17(10.7), suspending 5(3.1%), and opting out 4(2.5). Further, the study revealed some possible reasons for non-observance of maxims to be face-saving, emphasis, creating fake truth, convincing, appealing to emotions, and avoiding certain topics. The study concluded that, panelists on the Day Show exhibited preparedness and willingness to share their life experiences with their audience. Again, the number of instances of observance of the Grice’s maxims outnumbering non-observance also affirms how prepared these panelists were to share their experiences with others. These findings affirm the important role Grice’s cooperative principle plays in helping to understand in a conversation. The study recommends that Producers of The Day Show invite panelists who would be cooperative as possible and willing to share their candid opinions on selected themes as required at each stage of the conversation. This will ensure that conversations are seen as natural and possible to yield genuine and quality results.

Analysis of total quality management implementation in the small and medium fashion design enterprises in production of slit and kaba in the Accra Metropolis, Ghana

The current stud y sought to empiricall y determine the feasibilit y of implementing TQM principles and finding out its effects on the production of Slit and Kaba in small to medium garment production enterprises. The mixed method research design was used to conduct the stud y. A total of 138 participants were purposively sampled from the population of small and medium scale fashion enterprises in the Accra metropolis. Both questionnaire and interview were used as the main data collection instruments. Descriptive statistics, inferential and thematic analysis were used to analyse the quantitative and qualitative data collected. From the stud y it was discovered that TQM is fundamental to the achievement of high-qualit y products and customer satisfaction and retention and that TQM results in an increase in sales, effective customer service coupled with cost reduction and improved production practices all will inure to the benefit and prospects of the production houses and that also, firms lack qualit y culture in the industr y, lack of commitment towards the implementation of the concept into the operations of the firms in the industr y as part of the TQM implementation procedure. It was therefore recommended that awareness concerning TQM must be created among industr y pla yers about the benefits and potentials of implementing TQM in their operations and also, government should introduce a polic y to include contents on TQM as part of the curriculum of Higher Fashion Education in Ghana. There must be a persistent education and training for all workers to facilitate a shift in attitudes and working practice. Apparel manufacturing businesses in Ghana must focus their attention on satiating its clienteles b y affording qualit y garment and services.

Analysis of transitivity in Awoonor’s just to buy corn and Yeboah-Afari’s the sound of pestles

The study uses Halliday's transitivity theory as a framework to analyse how language has been used by Kofi Awoonor and Adjoa Yeboah-Afari to reveal how the African experience is represented from the Ghanaian perspective in their respective stories Just to Buy Corn and The Sound of Pestles. The primary focus is on the analysis of transitivity in the selected stories and how the interplay between processes, participants and circumstances is used as representation of the author‟s perception of the Ghanaian experience. Using the qualitative design and the interpretative content analysis, the study finds that material processes abound in both texts analysed. The dominance of material processes in the stories indicates the existence of a lot of physical actions in the African experience. The existential process types are used in the stories to describe the places where the setting of each story is set. They are also used to point to some of the challenges the characters face as well as their conditions before the narrative time to make readers fully appreciate their problems. The conclusion drawn from the study is that the selected stories use more primary process types than secondary types. The study confirms that the transitivity system can help in analysing clauses effectively and also helps us encode our experiences of the world. The study recommends that Systemic Functional Grammar is made an integral part of the English curriculum so that students will be abreast of the requisite skills for textual analysis.

Analysis of young banked and unbanked customers' usage, satisfaction, trust and loyalty for mobile money services in Ghana

This study assesses mobile money usage, satisfaction, trust and loyalty among young banked customers and unbanked customers in Ghana. Two models were developed for banked and unbanked customers and tested via partial least square (PLS) structural equation modelling (SEM) in SmartPLS. Data were collected from a cross-section survey of 700 mobile money users with response rate of 72.4%. The findings indicate that, for young customers without a bank account, satisfaction significantly influence customer loyalty whilst trust predicts active usage. Interestingly, however, the relationship between trust and loyalty to mobile money was insignificant but active usage lead significantly to customer loyalty. Despite the contextual limitation, this research has validated two theoretical models of antecedents of loyalty in mobile money context and provided implications for the planning and allocation of resources and capabilities that are required to enhance young consumers' trust, satisfaction, active usage and loyalty.

Analysis of Zika virus dynamics with sexual transmission route using multiple optimal controls

In this paper, we formulate and analyse a nonlinear optimal control problem for a Zika virus (ZIKV) infection model with sexual transmission route. An existing deterministic 11-dimensional autonomous system of differential equations is extended to include five time-dependent control functions, namely personal protection, condom use, vaccination, treatment and spraying of insecticide. The necessary conditions for the existence of optimal control quintuple are shown, and we determine the control strategies to minimize the spread dynamics of the ZIKV in the population at the minimum cost of control implementation. The derived optimality system is solved numerically to demonstrate the effectiveness of the different combinations of the five optimal controls in curtailing the transmission and spread of the disease. More importantly, we conduct a cost-effectiveness analysis on the combinations of at least four optimal controls to ascertain the most cost-effective strategy that can be used to hamper the ZIKV spread in the population. � 2020 The Authors

An Analysis ofImages of Contention and Violence in Dagara and Akan Proverbial Expressions

Proverbial expressions have typical linguistic and figurative features. These are normally captivating to the listener. The expressive culture of the Dagara and Akan societies is embellished by these proverbial expressions. Most African proverbs, express various images depicting both pleasant and unpleasant situations in life. Unpleasant language normally depicts several terrifying images particularly when threats, insults and other forms of abuse are traded vehemently. Dagara and Akan proverbs are no exceptions to this phenomenon. This paper seeks to examine images of contention and violence depicted in Akan and Dagara proverbial expressions. To achieve this, a variety of proverbs from Akan and Dagara were analysed for their meanings using Yankah’s and Honeck’s Theories. The result revealed that structurally, as with many proverbs, the Akan and Dagara proverbial expressions are pithy and terse. The most dominant images of contention and violence in these expressions expose negative values and perceptions about the people who speak these languages. Keywords: Akan, Dagara, Proverb, Imagery, Contention, Violence

Analytical pursuit of C.W.K. Mereku's ‘Asomdwee Hen’ operetta.

This article aims to introduce and analyse C.W.K. Mereku’s Asomdwee Hen, an operetta, which has been the most performed African oriented musical drama in Ghana. The work which combines drama with music tells the story of the faith of Christians on the birth of Christ. The article does not only examine the African musical compositional features but pulls out the aesthetics of this traditional musical drama through musical analysis and delves to unearth the relevance of the work in the field of practical African musical drama composition. It concludes that the potential vivifying catalyst of the work is seen in the several artistic multicultural vicissitudes of thought, such as drum patterns, tonality, vocal style and language, submitted to the musical treatment by the composer. Asomdwee Hen is indeed a fundamental platform for the creation of African musical drama and pursuit of its aesthetics

An analytical study of five selected works Of Walter Komla Blege

Walter K4mla Blege is a seasoned African art musician who uses his music to defend the cause of black Africans. He studied music at Mawuli Secondary School, Ho in the Volta Region of Ghana under the tutelage of Nicholas Zinzendorf Nayo and has continued by self-taught approaches to become a brilliant and prolific composer. This work, therefore, seeks to meticulously study and unearth the enviable compositional traits found in his works. It examines how he uses dances and other indigenous elements as fundamentals to drive home his desire for African art music composition. Five works out of his countless compositions were analysed using Sadoh and Tovey's descriptive approach. Under the methodology, the work utilises research tools of interview, observation, library research, internet exploration, and archival examination to gather data. The study establishes Blege's choral works as crucial in the annulment of the dogma of the church that forbids converts from participating in African music. Findings of the study described the illustrious career of Walter Blege as educationist, an administrator and an art music composer. The study also reveals him as somebody who expertly transcribes, repackages and translates music. Among his stylistic features is setting music to traditional dances with and without accompaniment. The study recommends that, like Walter Blege, other African art composers should adopt the inter-ethnic and intra-ethnic approaches in their compositions. Theologians should also look at him as a preacher due to the overly manner he uses music to preach the gospel in the context of Africa.

An analytical study of selected choral works of Cosmas Worlanyo Kofi Mereku

This study explores the compositional stylistic traits of C.W.K. Mereku through formal analysis of his choral works. It highlights the extent to which Mereku uses traditional idioms and styles in his compositions. Through descriptive research design and analytical approach, it was found out that Mereku usually has simple melodies and his usage of tunes to text in his compositions usually follows the speech surrogate or the sound culture of the owners of the language used. Furthermore, his choral compositions cover the following themes of categorization: Sacred, Patriotic, Secular and Institutional Anthems. Out of these categories, six pieces were selected based on their stylistic approach and the arrangement used in writing. The study suggested that composers must be conversant with the language to achieve well-organized syncretic compositions that cut across all events. It is important that old composers mentor young ones to ensure stylistic continuity.

Analyzing common errors in the use of English adjective clauses, a case study of St. Peter’s Catholic Basic School Ngleshie Amanfro

This study examined errors made in the adjective clauses by the students of St Peter‟s Catholic Basic School Ngleshie Amanfro. To achieve this, essays from 132 final year pupils were analyzed for different types of adjective clause errors. Interviews were also conducted to solicit information on trainees and teachers‟ view regarding adjective clause errors among students. The results are classified into two main categories: error types and causes of errors. The common errors committed by the participants were misuse or wrong use of relative pronouns, omission of relative pronouns, blend or use of both relative pronouns and personal pronouns and simple addition. Findings showed that participants committed more misuse errors than any types of adjective clause error identified in this study. The findings showed some major causes of these errors as: complexity of English language rules, students‟ poor reading habits, language transfer, inappropriate teaching methods and ignorance of the grammar rules or carelessness.

Analyzing grammatical errors in the written exercises of students of Boa Amponsem Senior High School

This study was conducted to help ascertain the grammatical errors students of Boa Amponsem Senior High School commit in their writing, the sources of these errors and how to remedy the problem. The researcher consulted various authorities who have written on grammar errors. He adopted the case study research design for the study and used sample population of four-hundred and forty (440) students who were randomly selected, and all the twenty (20) English Language tutors of the school to help collect the data. He also employed the research methods such as interviews, documents and observation to collect the data. Major findings from the use of these methods included: agreement errors, wrong use of tense (past/present, aspect, etc.), singular-plural errors, prepositional errors, article errors and spelling errors. The findings also looked at the sources of the grammar errors which were mother tongue transference, overgeneralization, incomplete rule application. The findings suggested strategies that can be used to curb this problem such as teachers’ and students’ exposure to English Language, differentiating grammar in English from native language, error identification and correction, and adequate time allocation for teaching grammar.

Anomaly detection framework for big data from Ghana perspective

An anomaly (deviant objects, exceptions, peculiar objects) is an important concept of the analysis. The volume and velocity of the data within many systems makes it difficult to detect and process anomalies for Big Data in real-time. Many anomaly detective systems count on the historical data for detecting behaviors�. Considering it as a problem to financial institutions in Ghana, the researcher proposed robust anomaly detection framework. The proposed frame work defines Spark stream, as part of Spark ecosystem, which stream data in real-time. Also, the proposed framework data model was build using SVM, Linear regression and Logistic regression as a package found in Spark MLlib. Additionally, the proposed framework was explained clearly to be implemented in real systems for financial institutions. � 2018 Newswood Limited.

The antecedents of credit risk in Ghana’s banking sector a robust least squares estimation approach

The purpose of this study is to investigate the antecedents of credit risk in Ghana’s banking sector within the context of policy rate, inflation rate, exchange rate, and cost efficiency. The study relied on 10-year secondary data from 18 Ghanaian-resident universal banks spanning from 2012 to 2021. The study adopted an explanatory research design and quantitative approach together with a panel robust least squares estimation technique. The results indicated that policy rate and cost efficiency have negative and significant impacts on credit risk whereas exchange rate and inflation positively predict credit risk. The study concludes that directing policy interventions towards policy rate, exchange rate, inflation and cost efficiency is the surest way of curbing credit risk in Ghana’s banking sector. It was therefore recommended to the Bank of Ghana to ensure an optimum policy rate that will protect the banking sector, control inflation and promote business activities in the country. Additionally, radical industrialization programmes should be embarked on to reduce the massive importation so as to curb the debilitating currency depreciation. Finally, banks should also ensure stringent internal control measures to enhance operational efficiency.

Antecedents of supplier relation quality in the ghanaian construction supply chain

Effective and efficient management of suppliers within a supply chain is an essential requirement for improving organisational performance within construction companies. However, factors inherent within the supply chain of supplier-buyer exchanges such as culture, politics, dependence and trust may influence supplier relationship quality (SRQ). This research therefore seeks to identify the influence that these factors have upon SRQ in the Ghanaian construction industry and develop a conceptual framework that explains the interconnectivity between them. A literature review is used to develop a conceptual framework of the antecedents influencing supplier relationship quality. Primary �perception� data obtained from 152 building material suppliers is used to test the proposed model using Partial Least Squares (PLS). Findings reveal that culture, politics, dependence and trust have a significant influence on relationship quality in supply chain collaborations amongst purchasers and suppliers of building materials. While politics has a strong influence on dependence, it also generates a negative influence on SRQ and trust. The research confirms the positive effect of trust and dependence in SRQ management and extends understanding of the influence of culture and politics. Practical implications suggest that managers of building material suppliers should focus upon building trust and dependence and be discouraged from over-reliance upon politics and political affiliations as a basis for long-term relationship building. � 2016, School of Engineering, Auckland University of Technology.
