With the development of the smart Internet of Things (IoT), an increasing number of tasks are deployed on the edge of the network. Considering the substantially limited processing capability of IoT devices, task scheduling as an effective solution offers low latency and flexible computation to improve the system performance and increase the quality of services. However, limited computing resources make it challenging to assign the right tasks to the right devices at the edge of the network. To this end, we propose a polynomial-time solution, which consists of three steps, i.e., identifying available devices, estimating device quantity, and searching for feasible schedules. In order to shrink the number of potential schedules, we present a pairwise-allocated strategy (PA). Based on these, a capability average matrix (CAM)-based index is designed to further boost efficiency. In addition, we evaluate the schedules by the technique for order preference by similarity to an ideal solution (TOPSIS). Extensive experimental evaluation using both real and synthetic datasets demonstrates the efficiency and effectiveness of our proposed approach.

MQTT protocol is publishing-subscribing model for IoT communication. In case of Quality of Services analysis, it is important to check the request and responses between publisher and subscriber. Any threat in communication channel is mostly leads to delay in operation. Hence, if we able to identify the delay parameter, we can suggest by means of QoS that there is a immediate need of security check for IoT system. As many IoT devices performed in unchecked, complicated, and often aggressive surroundings, safe-guarding IoT units present many different challenges. The key purpose for support quality degradation of IoT device interaction can be harmful attacks. Plenty of gadgets are often susceptible to port attacks/botnets hits, such as network attack events, which usually assessed by performing QoS Analysis. To start with factors affecting Quality of Services (QoS), in this paper we developed QoS evaluation algorithm “MQoS” for MQTT protocol and considered QoS-0 as an evaluation parameter. This paper refers the threat model which represents the flow of threats for proposed case study and can help to identify QoS by evaluating the possible communication threats. End–to-end device communication requests and responses are needed to be evaluated for large systems to get the actual QoS parameters for that system. For this reason the actual QoS tests will be conducted for third party applications.In this paper we presented results of MQTTv311 simulation for cooling sensor system.

In modern times, barbershop aka men's shaving places is the main choice of modern men to style their hair. The results showed that the popularity of Barbershop itself is due to the trend of the haircut, the classic hairdo. Classic hairstyle trends are also supported by the media which has a positive impact on popularity, hair fashion as a priority, knowledge about fashion is getting better, pomade trends. In general, customers want to get the best quality of services provided.Changes in customer haircuts or Barbershop customers are usually caused by changing trends or because they want to find new models that are more age-appropriate. The haircut catalog is a book that contains information on various haircut models that are made in the form of pictures and names of haircuts, where the names of haircuts are generally made in English.The problem that can occur in cutting hair is the lack of desires of the customer to the results of the hair stylist cut, it happens because the customer does not understand or do not remember the name of the desired haircut model. Crochemore Perrin's algorithm factored the right pattern so that pattern = right pattern left pattern. The matching phase of this algorithm consists of two parts, first matching the right pattern character from left to right, then matching the left pattern from right to left.Keywords: Barbershop, Android, Catalog, Crochemore Perrin

As políticas públicas para a educação infantil no Brasil, considerando as dimensões de oferta, acesso e qualidade apresentam-se lacunares quanto à garantia do direito da criança pequena à educação. Por meio de uma pesquisa exploratória, o objetivo deste estudo foi o de discutir tais “lacunas” por meio de sua identificação e discussão.  O estudo revela que acesso à vaga e a permanência da criança nessa etapa da Educação coloca como um dos desafios a diminuição das disparidades no acesso, sobretudo por razões socioeconômicas, visto que as crianças com famílias de menor ou nenhum poder aquisitivo são as que mais têm ficado à margem desse direito. O estudo revelou que os municípios precisam ampliar a oferta de atendimento, sem marginalizar a qualidade dos serviços ofertados, e não apenas oportunizando acesso, mas garantindo a permanência também em período integral.Palavras-chave: Educação infantil.

Through exploratory research, the purpose of this study was to discuss such “gaps” through their identification and discussion. The study reveals that access to the vacancy and the permanence of the child in this stage of education poses as one of the challenges the reduction of the disparities in access, especially for socioeconomic reasons. It is known that children with families with less or no purchasing power have been left out of this right. The study revealed that the municipalities need to expand the offer of care, without marginalizing the quality of services offered, not only providing access, but also ensuring full-time permanence.Keywords: Early childhood education.

The purpose of the present study was to explore the experience of the patients and hospital behaviour after the implementation of the no-class wards policy and its possible impact on the poor and non-poor patients provision and quality of care. This case study was conducted at Wates Hospital and purposeful sampling was used to yield participants. This study employed in-depth interviews with health care users district health care stakeholders, and focus group discussions with hospital healthcare professionals. The no-class wards policy had clearly demonstrated on improving the right to access to quality health care for the poor. The policy had been effectively reducing the experiences of patients on discriminatory treatment and improving quality of services. The policy also had an impact on increasing hospital utilization significantly among public insurance beneficiaries for both the poor and non-poor patients which supports the success of the implementation of the universal health coverage. Moreover, the policy had improved the assurance of quality of services. Future research needs to expand on our work to compare the implementation of no-class wards policy in other hospitals in different regions in Indonesia considering different local context such as local political issues, public expectations and other technical issues.
