VARIOUS KINDS OF MATRICES IN CYCLOTOMIC GRAPHS

The component matrix, Laplacian matrix, Distance matrix, Peripheral distance matrix, Distance Laplacian of the cyclotomic graphs and some properties are found. The D-energy, $D_{p}$-energy, $D^{L}$-energy and some indices of the cyclotomic graphs are determined. For the real symmetric matrices, matrices that attain the maximum $L, L_{s}$ and the minimum S are calculated. The Hausdorff distance and optimal matching distance of the cyclotomic graphs are evaluated.

Spinor vacuum and C, P, T inversions

We have developed the theory of Clifford reflections and extended spacetime inversions. This extended spacetime has two additional dimensions associated with the presence of internal degrees of freedom of spinors. Inversions C, P, and T contain not only reflections of the basis Clifford vectors and transformations of basis spinors, but also transformations of the components of vector and spinor quantities. The research is carried out on the basis of algebraic quantum field theory using the superalgebraic representation of spinors as well as the 8-component matrix representation of spinors. We have proved that due to the presence of internal degrees of freedom of spinors, there are two vacua, the vacuum of our Universe and an alternative vacuum. The inversion operators C and T transform the vacuum into an alternative one, and therefore cannot be operators of the exact symmetry of our Universe.

CSR Practical Orientation in Small Medium Enterprises (SMEs): A Case Study in Solo City Indonesia

This study explores empirical data on the orientation of CSR practices to SMEs in City Surakarta seen from CSR practices that are employee, market, and environment-oriented as a whole. The sample in this study was 90 SMEs in the Surakarta area. The method used in this research is a survey with data analysis using Confirmatory Factor Analysis (CFA). Before the survey, a pilot study was conducted on 10 SMEs actors to test the instrument’s validity and reliability. The results showed that the most dominant CSR practices at SMEs in City Surakarta were the community orientation indicated by the rotated component matrix table of 0.904 and the market orientation indicated by the rotated component matrix table of 0.876. Both orientations are more dominant than other orientations.

Analisis Dimensi Brand Trust Terhadap Brand Loyalty (Studi Pada Pengguna Simcard Im3 Mahasiswa Febis Unikarta )

The purposes of the study were analyzing the effect of dimensions of brand trust on brand loyalty both partially and simultaneously. Beside that, to find out the dominant variable in influencing brand loyalty. The analytical tool used was a factor analysis with 75 respondents. Based on the results where the KMO table and Barlett’s test was obtained at 0.887 with a significant value less than 0.05(0,000 ≤ 0, 05). It can be concluded that the dimensions of brand trust have a significant and simultaneous influence on brand loyalty. The result also show the analysis of anti image correlation where each variable gives a contribution to the value of brand loyalty where each variables contributes: brand predictability (X1) 0,905; brand likings (X2) 0,895; brand competence (X3) 0,858; brand reputation (X4) 0,898 and trust in company (X5) 0,92. All these number above 0,5 and sig is far below 0.005 (0,000<0,000). It can be concluded that the dimensions of brand trust have a significant and partial influence on brand loyalty Based on the results of the component matrix analysis brand competence has the most dominant influence on the formation of brand loyalty IM3 brand with the highest correlation value 0,932. Keywords: Brand Trust, Brand Loyalty.

Optimization of Solvent and Extractive Distillation Sequence Considering Its Integration with Reactor

The integration of reaction and extractive distillation system is beneficial for reducing the process cost. A systematic method is proposed to identify the optimal solvent, solvent-to-feed ratio, extractive distillation sequence and reactor operating conditions based on the integration of reactor and extractive distillation. The non-key component matrix method is used to generate the extractive distillation sequences. The proposed method can be used to evaluate different solvents, solvent-to-feed ratios, as well as the extractive distillation sequences; the optimal extractive distillation parameters corresponding to the minimum total annualized cost (TAC) can be identified considering different operating conditions. For the selective hydrogenation of benzene to cyclohexene process, the minimum total annualized cost of unit desired product, 4.01 $·kmol−1, is achieved when the reactor’s inlet temperature is 333 K, solvent N-Formylmorpholine and sequence S2 are employed, and the solvent-to-feed ratio is 4.

INNOVATION MANAGEMENT IN HOTELS INDUSTRY IN AQABA SPECIAL ECONOMIC ZONE AUTHORITY; HOTEL CLASSIFICATION AND ADMINISTRATION AS A MODERATOR

The Paper investigates innovation management in hotels classified in the Aqaba Special Economic Zone Authority: hotel classification and management as a moderator. In order to arrive for the result in factor analysis we used the SPSS version 20 in analyzing 23 items of the Likert scale, before performing axial component analysis, the data’s suitability for factor analysis was evaluated. Through by Rotation Sums of Squared Loadings result; we have four items by rotated component matrix was detected the strong loading axial factors. Creativity is one of the most common and prevalent terms in management literature nowadays, moreover, it has become one of the foundations of success and competition between organizations in terms of their ability to excel, create and innovate, which grants the necessity of developing their concepts and administrative methods to set the scene for workers for creativity, and transfer of accumulated knowledge and options.

Prediction and Identification of Antioxidant Peptides in Potato Protein Hydrolysate

Principal component analysis (PCA) was used to cluster the possible amino acid compositions of antioxidant peptides in potato protein hydrolysate (PPH). The antioxidant peptides exhibiting high ABTS+• scavenging capacity were isolated with the procedure of ultrafiltration, gel filtration, and preparative RP-HPLC and identified by UPLC-MS/MS. Phe, Tyr, and His were shown to group together with ABTS+• scavenging capacity in component matrix plot. Three prominent peptides, namely, Phe-Tyr, Tyr-Phe-Glu, and Pro-Pro-His-Tyr-Phe, which matched the sequence of patatin and were made up of Phe and Tyr, were identified. The peptide Tyr-Phe-Glu demonstrated antioxidant activity against Caco-2 cell oxidation induced by H2O2. The results suggested that multivariate analysis could be used to predict the amino acid compositions of antioxidant peptides.

ANALISIS FAKTOR-FAKTOR YANG MEMPENGARUHI PERILAKU KONSUMEN UNTUK MEMBELI MOBIL TOYOTA AVANZA (STUDI KASUS PADA PT. ASTRA INTERNATIONAL TBK AUTO 2000 MEDAN)

The purpose of this study was to determine and analyze the most dominant factors influencing consumer behavior to buy Toyota Avanza cars (case study at PT Astra International Tbk Auto 2000 Medan). The benefits of research for the development of science, especially in the field of consumer behavior, as a reference in conducting further research. The number of samples is 100 respondents, the types of data used are primary and secondary data, and the method of collecting data through questionnaires and documentation, the method of data analysis is used factor analysis. From the results of research and discussion obtained the KMO Measure of Sampling Adeguacy (MSA) Figures of 0797 with a significance level of 0,000. Because the KMO value is above 0.50 and is significant at 1 percent, the data are quite feasible for further analysis using factor analysis. Component Matrix shows that the variables analyzed are not clearly included in which factors. After the rotated component matrix is performed, the twenty variables studied are clearly included in factor 1, factor 2, factor 3, factor 4 and factor 5. The dominant factors affecting consumer behavior to buy Toyota avanza in PT Astra International Auto 2000 Medan are car prices, car brands, lifestyle, income levels and experience. The most dominant factor influencing consumer behavior is the price of a car. Suggestions that are recommended should the company target and intensify marketing in the community who work as entrepreneurs. This is based on the work of entrepreneurs who demand high mobility and have strong capital in conducting transactions, especially car purchases. Affordable and rational prices need to be considered by the company. Companies can also make the payment system look lighter by collaborating with finance companies that have a good track record.
