Necessary and Sufficient Conditions Where One Γ-Semigroup is a Γ-Group
Sabri Sadiku
Journal of Modern Mathematics and Statistics , 2012, DOI: 10.3923/jmmstat.2010.44.49
Abstract: In this study, researchers have studied the Γ-algebraic structures and some characteristics of them. According to Sen and Saha, we defined algebraic structures: Γ-semigroup, Γ-regular semigroup, Γ-idempotent semigroup, Γ-invers semigroup and Γ-group. Theorem 2, 3 and 4 proves the existence of Γ-group and gives necessary and sufficient conditions where one Γ-semigroup is a Γ-group. Finally, theorem 5 shows necessary and sufficient conditions where one Γ-regular semigroup is a Γ-group. In addition, for every Γ- algebraic structure that we mentioned before we give an original example.
Deutsche und albanische Phraseologismen mit Tierbezeichnungen im Kontrast
Sadiku, Milote
Linguistik Online , 2011,
Abstract: The object of this article are animal idioms in contemporary German and Albanian: the article treats those units that denote animal names in their formal structure with phraseological, figurative meaning. The aim of the article is to identify and describe the differences and similarities between these two languages from the viewpoint of a contrastive analysis. The German phraseology has often been the subject of inter-linguistic comparisons. However, this can not be claimed for the German – Albanian language analysis. In this article, some similarities and differences in animal symbolism in the German and Albanian phraseology are illustrated by typical examples, and equivalence relations between the German and Albanian animal idioms are identified.It can be concluded that the animal names in idiom units indicate positive and negative characteristics or behavior of people. One result is that the negative semantic characteristics predominate in both languages. The animal name depends on a concrete idiom not only from the ideas and values that are attributed to an animal in a language community, but also from the already existing structures and pragmatic rules in a concrete language.

Fuel Saving and Control for Hybrid Electric Powertrains  [PDF]
Mohamed Zaher, Sabri Cetinkunt
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.55035

This paper focuses on comparing the performance of the embedded control of a hybrid powertrain with the original and downsized engine. The main idea is to store the normally wasted mechanical regenerative energy in energy storage devices for later usage. The regenerative energy recovery opportunity exists in any condition where the speed of motion is in the opposite direction to the applied force or torque. A rule based optimal robust control algorithm is developed and is tuned for different work cycles. A comparison of the fuel savings using the hybrid system with the original and downsized engines is performed.

International Journal of Intelligence Science (IJIS) , 2013, DOI: 10.4236/ijis.2013.33015

There are few changes that took place in Iraqin many fields during the past few years; the financial aspect is one of the fields that undergone this change. The change has positive impact because it increases the revenue inIraqfrom the oil exports. The National Insurance Company is one of many companies that belongs to the Ministry of Finance inIraqand has affected directly from this change in term of increasing the number of the insurers which we will discuss in this research. The aim of this research is to forecast the insurance premiums revenue of the National Insurance Company between the years 2012 to 2053 using Artificial Neural Network based on the actual annual data of the insurance premiums revenue between the years 1970 to 2011. The data analyses results of this research show that the growth indicator of the insurance premiums revenue for the next 41 years is approximately 120%, the Mean Squared Error is the average squared difference between outputs and targets. Lower values are better. Zero means no error and the regression values are very high. The estimations and forecasts of the insurance premiums revenue using Artificial Neural Network confirmed to be strong and useful to deploy it for forecasting the insurance premiums revenue.

International Journal of Intelligence Science (IJIS) , 2013, DOI: 10.4236/ijis.2013.34017

This paper aims to demonstrate the importance and possible value of housing predictive power which provides independent real estate market forecasts on home prices by using data mining tasks. A (FFBP) network model and (CFBP) network model are one of these tasks used in this research to compare results of them. We estimate the median value of owner occupied homes in Boston suburbs given 13 neighborhood attributes. An estimator can be found by fitting the inputs and targets. This data set has 506 samples. ousing inputs” is a 13 × 506 matrix. Thehousing targets is a 1 × 506 matrix of median values of owner-occupied homes in $1000’s. The result in this paper concludes that which one of the two networks appears to be a better indicator of the output data to target data network structure than maximizing predict. The CFBP network which is the best result from the Output_network for all samples are found from the equation output = 0.95 * Target + 1.2. The regression

Consumer’s Purchase Intention towards Luxury Retailer’s Social Media Advertisements —A Case Study of a Shoe Retail—UAE-Dubai Mall  [PDF]

Social Networking (SN) , 2019, DOI: 10.4236/sn.2019.81003
Digital marketing is considered the preferred method comparing to traditional marketing nowadays [1], but is it true for luxury and expensive products? Since the perception prevails that the concepts “luxury” and “digital” are quite incompatible [2], this paper aims to explore the effectiveness of digital marketing advertisements of luxury retailers, while also exploring consumer’s purchasing intent based on the viewing of such promotions. The overall goal is to provide a model of luxury purchase behaviour through harnessing social media. As a constructionist ontology-based researcher, I believe in multiple versions of reality which can evolve based on my target consumer experiences [3]. My epistemological stance is interpretivism with a subjective approach, inductively interacting with consumers to better understand what this “truth” means to them, incorporating textual material to support the analytical interpretations [4]. It is hoped this paper will inform fashion brands marketers about social media practice to achieve creation of purchase intention and ultimately achieve target sales. The paper is useful to both practitioners and academics in the fields of social media marketing and purchase intention. The research provides some initial insights into consumer perspectives of social media ads and online purchase behaviour.

Social Networking (SN) , 2019, DOI: 10.4236/sn.2019.82006
Abstract: Organizational culture can be defined as the intermixture between values, visions, language, behaviors and beliefs that shape an entity’s unique operating environment. Although the personality of a business may be difficult to articulate, it can have a huge impact on how members of an organization deal with each other, customers and other stakeholders. A good organizational structure facilitates attainment of objectives through proper coordination of all activities. Recently, practitioners and academics aim to identify type of culture before starting a project. Accepting and conducting research is a project by itself, in which, many organizations have a flexible appetite to conduct research to help their objectives. This paper demonstrates the identification of appropriate frameworks to prepare an audit of the organizational culture towards research informed decision-making and management, which means that the paper will analyze definitions of what research means before conducting the organizational research-culture audit to understand the research appetite of the organization.
Protein Sparing Effects of Lipids in The Practical Diets of Oreochromis niloticus (Nile tilapia)
AM Orire, SOE Sadiku
Nigerian Journal of Basic and Applied Sciences , 2011,
Abstract: A feeding trial was conducted to establish the protein sparing effects of various lipid sources in Oreochromis niloticus fingerlings (mean weight 8.05 ±0.05g) for 8 weeks. Nine experimental diets and one commercial reference diet was used for the trial. The experimental diets comprised of three levels of lipid (L) and protein (P) designated as 15P : 25L, 10P : 30L and 5P : 35L ratios. Three lipid sources used were groundnut oil, palm oil and fish oil. The result obtained showed significant differences (P<0.05) among the lipid sources. Fish oil showed significant differences in the mean weight gain (MWG), specific growth rate (SGR), feed conversion rate (FCR), and apparent net protein utilization (ANPU) for all the treatments. The carcass compositions was also significant (P<0.05) in moisture, lipid and ash which resulted in protein sparing at 10% inclusion level thereby bringing down crude protein inclusion level to 30%. Groundnut oil did not show significant difference (P>0.05) in the MWG, and SGR for all the treatments, but showed significant difference (P<0.05) for the FCRs, PERs and ANPUs. The palm oil based diets also gave significant difference (P<0.05) in the MWG, SGR, PER and ANPU. There was significant difference (P<0.05) in the carcass compositions. Groundnut oil was observed to spare protein at 10% inclusion level while palm oil spared same at 15% inclusion level. These findings will ensure reduction in the crude protein inclusion level in the diets of O. niloticus using these lipid sources.
