Abstract: |
Regardless of the products, quality is the most crucial concern for all manufacturers in any manufacturing system. Quality management is a collection of procedures and instruments that can improve the overall system performance of a manufacturing facility. The dynamic nature of today's business climate and intense rivalry in the market have made quality tools and continuous improvement (CI) essential for long-term success and overcoming obstacles. The methodology of automating quality assurance with cloud computing is also explored in this study. Given how popular cloud computing has become lately. An increasing number of manufacturers are thinking about switching to a cloud-based quality system for their quality management. Because of this, the cloud's power, agility, and cost advantages are now essential for surviving in today's dynamic and uncertain manufacturing environment. Thus, utilizing machine learning methods and cloud computing, this work has provided a service-based proposal system for visual quality assurance. The model's accuracy in detecting defects in manufactured parts and response time are assessed. The model's average accuracy was estimated to be approximately 93%, while the average reaction delay was estimated to be approximately 8 seconds. |

Abstract: |
Let G be a nontrivial connected graph. A dominating set D⊆V(G) is called a doubly connected dominating set of G if both {D} and {V(G)\D} are connected. Let D be a minimum doubly connected dominating set of G. If S⊆V(G)\D is a doubly connected dominating set of G, then S is called an inverse doubly connected dominating set of G with respect to D. Furthermore, the inverse doubly connected domination number, denoted by γcc−1(G), is the minimum cardinality of an inverse doubly connected dominating set of G. An inverse doubly connected dominating set of cardinality γcc−1(G) is called γcc−1-set. In this paper, we characterized the inverse doubly connected domination in the join and cartesian product of two graphs and give some important results. |

Abstract: |
Sustainable housing design is a key component of achieving the Sustainable Development Goal 11 (SDG-11), which aims to make cities and human settlements inclusive, safe, resilient, and sustainable. However, cultural influences are often overlooked or neglected in the design process, leading to potential conflicts and mismatches between the intended outcomes and the actual needs and preferences of the users. This paper presents a systematic review of forty-nine published journal articles from 2009 to 2023 that explore the relationship between cultural influences and sustainable housing design in different contexts and regions. The review follows the PRISMA guidelines and uses a mixed-methods approach to synthesize the data from descriptive statistics, thematic analysis, and meta-analysis. The results reveal that cultural influences have significant impacts on various aspects of sustainable housing design, such as energy efficiency, thermal comfort, indoor air quality, water management, waste management, materials selection, spatial organization, aesthetics, and social cohesion. The paper also discusses the challenges and opportunities for integrating cultural influences into sustainable housing design and provides recommendations for future research and practice. |

Abstract: |
The use in this work of a diet model differentiated between Neanderthals and early modern humans, based on the need for a diet rich in protein to maintain robust morphology and muscle hypertrophy in elite weightlifting and throwing athletes, with anatomical adaptations similar to Neanderthals, allows establishing an increase of 81.92% of the population of modern humans with respect to Neanderthals. This must have played an essential role in the extinction of the latter, due to the competition to obtain a greater amount of daily protein (121.89 gr/day for each Neanderthal versus 67 gr/day for each modern human) to maintain 30% more muscle mass (Boyd et Silk, 2001, Arsuaga et al., 2015, Carretero et al., 2018, García-Martínez et al., 2018). |

Let G bea connected simple graph. A dominating set S⊆V G is called a perfect dominating set of G if every u∈V G \S is dominated by exactly one element of S. Let D be a minimum perfect dominating set of G. A perfect dominating set S⊂ V G \D is called an inverse perfect dominating set of G with respect to D. A disjoint perfect dominating set of G is the set C=D∪S⊆V(G).

Let G be a connected simple graph. A set S⊆V(G) is a restrained dominating set if every vertex not in S is adjacent to a vertex in S and to a vertex in V(G)∖S. A set S of vertices of a graph G is an outer-restrained dominating set if every vertex not in S is adjacent to some vertex in S and V(G)∖S is a restrained set. The outer-restrained domination number of G, denoted by γr(G) is the minimum cardinality of an outer-restrained dominating set of G. An outer-restrained set of cardinality γr(G) will be called γr - set. In this paper, we initiate a study of the concept and give the characterization of the outer-restrained dominating set in the join and corona of two graphs. |

Abstract: |
Let 𝐺 be a graph. A dominating set 𝐷⊆𝑉(𝐺)is called a secure dominating set of 𝐺 if for each vertex 𝑢∈𝑉(𝐺)∖𝐷, there exists a vertex 𝑣∈𝐷 such that 𝑢𝑉 ∈ 𝐸(𝐺) and the set (𝐷∖{𝑣})∪{𝑢} is a dominating set of 𝐺. If every 𝑢∈𝑉(𝐺)∖𝐷 is adjacent to exactly one vertex in 𝐷, then 𝐷 is a perfect secure dominating set of 𝐺. Let 𝐷 be a minimum perfect secure dominating set of G. If 𝑆⊆𝑉(𝐺)∖𝐷 is a perfect secure dominating set of 𝐺, then 𝑆 is called an inverse perfect secure dominating set of 𝐺 with respect to 𝐷. A disjoint perfect secure dominating set of 𝐺 is the set 𝐶=𝐷∪𝑆⊆𝑉(𝐺). Furthermore, the disjoint perfect secure domination number, denoted by 𝛾𝑝𝑆𝛾𝑝𝑆(𝐺), is the minimum cardinality of a disjoint perfect secure dominating set of 𝐺. A disjoint perfect secure dominating set of cardinality 𝛾𝑝𝑆𝛾𝑝𝑆(𝐺) is called 𝛾𝑝𝑆𝛾𝑝𝑆-set. In this paper, we initiate a study of the concept of disjoint perfect secure domination in graphs and characterize this type of domination in graphs under some binary operations, namely the join and corona of two graphs.. |

International Journal of Latest Engineering Research and Applications, pp 88 - 94, Vol 09 - No. 01, 2024 |
Abstract: |
The Public services to the people carried out by the government from national to village level, and the people of Timor-Leste continue to cry out for unsatisfied public services. The Administrative Decentralization Policy is a way to distribute the power of the central government to the municipal government to carry out the necessary public services at the local level. Therefore the Government's Administrative Decentralization Policy is set out in Article 72° of the Republic Democrat of Timor Leste Constitution as in paragraph (1) states that "the local power of the people who are collective in the country with representative bodies will be created to organize the participation of each citizen on the solution of their own problems in their community and to promote local development, and not affect the participation of the state". Also referred to in Article 5 of the Republic Democrat of Timor Leste Constitution on Decentralization is as in paragraph (1) The State respect, within its national organisation, the principle for the sharing of the powers of the Public Administration, (2) The law shall establish and strengthen the different characteristics of the country, as well as the administrative competence of the bodies. Based on the above, the following problems are formulated: How is the Administrative Decentralization Policy Strategy for Quality Public Service to the People? The purpose of the research is to identify, analyse and describe the administrative decentralization policy strategy for conducting quality public services to the people. The theory that serves as a basis is the institutional theory by Di Maggio & Powell (1983). This research used qualitative descriptive methods. Data sources are primary data and secondary data. With data collection techniques, observation, interviews and documentation. And using data analysis techniques from experts Miles & Hubermen (1992:20), such as: data collection, data presentation, data reduction and valid data verification. The research findings show that, in Timor-Leste, the Government has started implementing administrative decentralization, to approach public administration services to the people, who are currently in the phase of territorial administrative deconcentration. The Government has also formulated laws, decree-laws, ministerial diplomas, government resolution, human resources preparation and preparation of facilities and budgets, to carry out administrative decentralization policies, which in the next phase will be held the Municipal elections so that the people of each Municipality can elected their local national bodies. |

Abstract: |
The ternary liquid-liquid equilibrium data of the biodiesel-methanol-water system involved in biodiesel production provides important tools for the development and design of the equipment. In this investigation, the effects of temperature and amount of beef tallow in corn oil on ternary phase equilibrium data for the system of biodiesel-methanol-water were experimentally determined. The biodiesel samples (0%, 10%, and 20% v/v beef tallow) were produced using the mixtures of corn oil and beef tallow with methanol (methanol to oil: 1/6, n/n) using potassium hydroxide of %1 (w/w) at 60 °C. The solubility data were determined using the cloud point titration method for biodiesel-methanol-water systems at temperatures of 25 °C, 35 °C,45 °C, and at atmospheric pressure. It was found that the effect of temperature on the solubility curves of the ternary liquid-liquid system of biodiesel-methanol-water was negligible at low methanol compositions but had little effect at high methanol compositions. The ternary liquid-liquid solubility curves of biodiesel-methanol-water systems did not significantly change with increasing the beef tallow concentration in corn oil. |

Let G be a connected simple graph and let D be a minimum dominating set of G. A dominating set S⊆V G ∖D is an inverse dominating set of G with respect to D. The set S is called a secure inverse dominating set of G if for every u∈V G ∖S, there exists v∈S such that uv∈E(G) and the set S∖ v ∪{u} is a dominating set of G. The secure inverse domination number of G, denoted by γs−1 (G), is the minimum cardinality of a secure inverse dominating set of G. A secure inverse dominating set of cardinality γs−1 (G) is called γs−1 −set. In this paper, the researchers initiate a study of the concept of secure inverse domination in graphs and characterize the secure inverse dominating set in the join of two connected simple graphs. |

Abstract: |
With the vast spread of automation, the significant demand for communication services, adding IoT to the Internet, and the corresponding huge increase and sophistication in malicious attacks utilizing system vulnerabilities to penetrate systems. Identification and Authentication are heavily used in every access trial towards any electronic resource and communication networks. The traditional approach to coping with such challenges is using passwords, encryption, Secure ID, Firewall, Etc. More safety methods use Biometrics, which suffer from spoofing. The access control market is a fast-growing and highly volatile market that poses significant challenges for investors seeking to make secured decisions. As the market continues to evolve and become more mainstream, there is a growing demand for new identification and authentication technologies. This paper proposes expanding the number of features extracted from a 3D image, with unique features evolved during the generation of the 3D image of the prospect at the access control stage. We mounted two identical 2D cameras on the same bar, allowing the adjustment of the distance between the two mounted cameras. The two cameras are simultaneously activated, generating a unique 3D image, including some distortion. This stage is executed at the person enrollment process and repeated at the access stage, providing an enhanced, unique, and cannot be faked Authentication. Experiments support the proposed approach. |

Credit risk is at the heart of banking concerns today. However, granting credit is a complex act; it is linked to risks whose coverage becomes a safeguard principle. In this context, it is necessary to carry out assessments in order to limit these risks. Our study has made it possible to show, on the basis of the work of the Basel Committee, the relevant valuation method with regard to the requirements of Basel II and Basel III. For this purpose, the “standard” and “IRB” methods were used. |
