Root-Cause Metric Location for Microservice Systems via Log Anomaly Detection

Microservice systems are typically fragile and failures are inevitable in them due to their complexity and large scale. However, it is challenging to localize the root-cause metric due to its complicated dependencies and the huge number of various metrics. Existing methods are based on either correlation between metrics or correlation between metrics and failures. All of them ignore the key data source in microservice, i.e., logs. In this paper, we propose a novel root-cause metric localization approach by incorporating log anomaly detection. Our approach is based on a key observation, the value of root-cause metric should be changed along with the change of the log anomaly score of the system caused by the failure. Specifically, our approach includes two components, collecting anomaly scores by log anomaly detection algorithm and identifying root-cause metric by robust correlation analysis with data augmentation. Experiments on an open-source benchmark microservice system have demonstrated our approach can identify root-cause metrics more accurately than existing methods and only require a short localization time. Therefore, our approach can assist engineers to save much effort in diagnosing and mitigating failures as soon as possible.
Using the ARAIG Haptic Suit to Assist in Navigating Firefighters Out of Hazardous Environments

The field of search and rescue (SAR) has not yet fully benefited from strides in haptic technologies. In this research, we seek to rectify this issue by proposing a novel application of IFTech's “As Real As It Gets” (ARAIG) wearable haptic suit for firefighters. First, we examine recent research in this field in order to lay down the groundwork for our project. Next, we present a wearable haptic system in which the ARAIG suit is outfitted with peripheral sensors in order to track the emergency responder's path; the system will then recreate the path and relay exit directions via haptic feedback to the wearer. Thus, the first responder does not have to dedicate more attention than necessary to remembering their entry path. Finally, the future of this project is outlined, which includes a physical implementation of this proposed system.
Application of a Low Frequency, Low Power Radio Frequency Positioning System for Real Time Indoor Positioning

This paper focuses on the design and application of low power and low-frequency localization system using received signal strength indication (RSSI). The receiver will wake up from sleeping mode by a modulated magnetic field emitted from a transmitter module. Then it will send messages containing the Received Signal Strength Indication (RSSI) via WiFi with Message Quest Telemetry Transport (MQTT) protocol to an MQTT broker. Using the magnetic coupling effect and RSSI ranging, the system is a unique candidate for low power security-positioning purposes.
Switchable Slant Polarization Filtering Antenna Using Two Inverted Resonator Structures for 5G Application

This study presents a novel design of two filtering antennas with a +45° and −45° slant polarization, using the co-design of a third-order filter and a rectangular patch antenna. Slant polarization is obtained by directing the surface current that flows to the radiator by applying two parallel inverted resonators in the transmission line. The resonators consist of two parallel strips with alternate open and short circuits at each end and the 45° and −45° polarization is determined from these short circuit positions. The rectangular patch antenna is fed using proximity coupling, and it is parallel to the resonators. The filtering antennas provide not only 45° slant polarization, a flat gain response but also a controllable bandwidth. Operating at 4.65 GHz for 5G application, the antennas have a controllable bandwidth range from 5.9% to 8.4% without affecting the polarization and center frequency. The gain responses are filter like and attain the maximum value of 6.82 and 6.69 dBi at 4.7 GHz. This design needs no extra component or rotation of the radiator and transmission line because the inverted resonators can switch the polarization to be +45° and −45°. The results of the 45° and −45° polarization filtering antenna simulation and experiments are consistent with each other.
SECURING MULTIHOP NETWORK BY DETECTING AND LOCATING SECURING MULTIHOP NETWORK BY DETECTING AND LOCATING POLLUTION ATTACKS USING SPACEMAC. POLLUTION ATTACKS USING SPACEMAC.

-It has been widely observed that providing security is one of the challenging task in Wireless sensor network(WSN). Program images need to be updated continuously as network programming happens in WSN. Many Networking protocols provide an efficient way to update these program images running on sensor nodes. One of the cryptographically strong protocol called DELUGE exists to address this challenge, but it involves high computational cost such as power consumption and communication costs. So Multiple one way key chain is proposed to secure a multihop network programming protocol which is lower in power consumption and communication costs. Even though one way key chain is used to provide security, network with static topology is considered. Network is made dynamic by adding mobility nodes to it. But the extra node added may not always be the genuine node. If it is an attacker node, there can be several pollution attacks. Attacker node travels through the network, and pollute the entire network. Wirelesss sensor network may not be able to detect these pollution attacks. In this paper, we are proposing a MAC scheme called Spacemac. It expands the network by adding nodes to it. Using SpaceMac, i) it detects the polluted packets early at the intermediate nodes. ii) it identifies the exact location of an attacker and eliminates them.
Research on Vibration Prediction Method of Aircraft External Stores Based on Deep Belief Network

This paper proposes a method for predicting the vibration environment of aircraft external stores based on deep belief network, which based on the relationship between the vibration environment, pressure altitude and Mach number of the aircraft external stores in flight. Firstly, GJB 150.16A empirical formulas were analyzed and then generating simulation data, which a total of 7470 sets. Secondly, linear regression and deep belief network models were set up respectively, and deep belief network number of hidden layer node was optimized, then the expected errors of two methods were compared and analyzed, including root mean square error (RMSE), mean absolute error (MAE) and mean relative error (MRE). Finally, DBN method was applied to a case for prediction the vibration of a certain aircraft store, intending to verify the feasibility and accuracy of DBN method. The results show that the DBN model can fully characterize the non-linear relationship between the pressure altitude, Mach number and RMS value of the aircraft external stores in the flight environment, and the overall expected effect is better than linear regression. The expected mean relative error is less than ± 3 dB. This method has provided a new way to predict the vibration environment of aircraft external stores, and is of great significance for PHM in the whole life of aviation weapon equipment.
Effect of Light Quality on Micropropagation and Some Morphological Properties of Cadaman Avimag (Prunus persica × P. davidiana ) Rootstock

Cadaman Avimag rootstock is widely used for almonds and peaches. The purpose of this study was to investigate the effect of light quality on micropropagation, and some morphological and physiological properties of this rootstock. Single node explants were cultured on WPM and MS media containing three levels of BA (0, 1 and 2 mg L -1 ) and three levels of NAA (0, 0.05 and 0.1 mg L -1 ). WPM medium containing 2 mg L -1 BA and 0.1 mg L -1 NAA was selected for different light quality treatments including fluorescent, red, and red+blue lights. Results showed that light quality had a significant effect on shoot proliferation, length and diameter, node number, shoot fresh and dry weights, leaf thickness, stomata number, and chlorophyll concentration. Red light resulted in higher shoot diameter, but crunchiness and lack of proper shoot growth. Moreover, red light produced the lowest amount of chlorophyll in the explants. Leaf thickness and its structural layers under the red light were the lowest among different treatments. Combined red+blue light in many factors resembled fluorescent light but induced more chlorophyll and a larger stomata size. The quality of light influenced the growth of this rootstock in vitro, and affected the stem and leaf vegetative traits.
Development and Sustainable Tourism Strategies in Red Islands Beach, Banyuwangi Regency

Red Islands Beach in Banyuwangi is included in the Provincial Tourism Strategic Area (KSPP). It is an example of the application on tourism management by the community, due to the existence of the community group (POKMAS). Increasing the number of tourists each year causes the need for a sustainable tourism development strategy that also involves the surrounding community to maintain environmental conditions that continue to be sustainable. So, this study aims to formulate a policy of developing sustainable marine tourism on Red Islands Beach in the Banyuwangi Regency. Data was obtained by conducting FGDs and distributing questionnaires to 10 key informants consisting of the Chairperson of Pokmas, the Homestay Manager, the Chairperson of BUMDES in Sumberagung Village, Academics, Ecoranger, Restaurant Managers, and the Management of Waste Banks. The data was analyzed using a SWOT analysis strategy to describe internal factors (IFAS) and external factors (EFAS). The results of the scoring IFAS showed the value of the Strengths (3.337) and weaknesses (2.979), while external factors showed value of opportunity (3.135) and threats (3.224). The strategy that can be applied based on this analysis is Concentric Diversification Strategies. These strategies focus on adding products and services related to the tourism destination, which uses Weakness and Threat (W-T) components. This strategy will overcome weaknesses and minimize threats on Red Islands Beach. Some points that can be carried out in this strategy are increasing human resources, providing education to the community, and negotiating with other interested parties in the Marine Tourism Region of Red Islands Beach. Keywords: Red Island Beach, sustainable tourism, SWOT.
QUALITY CONTROL OF PNEUMATIC SPRAYING IN TOMATO

Tomato is a vegetable of great importance on the national scene. One of the problems of this culture is the great susceptibility to attack by pests and diseases. Thus, one of the most used practices is chemical control with phytosanitary products. The objective of this study was to evaluate the technical parameters of pneumatic spraying in tomato culture, through the study of the volumetric index and the population of spray droplets, aiming to reduce the spray volume, obtain the best efficiency and the social and environmental safety of the applications. The study of the droplet population was performed using water-sensitive paper labels. These labels were placed in the canopies of the tomato plants at three different heights and two positions. The sprays were made using a pneumatic backpack sprayer. After applying the syrup (dye + water), the water-sensitive paper labels were collected and subjected to the coverage and droplet density analyses by the computer program “CIR” version 1.5. The pneumatic sprayer proved to be efficient for the application of phytosanitary products in the tomato. The percentage of the target covered area ranged from 2.1 to 8.3% for volumetric indices as a function of thirds and positions, whereas the density of droplets ranged from 145.4 to 690.1 drops cm-2 for thirds and positions of the tomato plants evaluated. Finally, the volumetric index of 5 mL m-3, with a consequent spray volume of 50 L ha-1, met the parameters of a quality spray.
REVIEW OF EDGE DETECTION ALGORITHMS FOR APPLICATION IN MINIATURE DIMENSION MEASUREMENT MODULES

Continuous improvement of semiconductor chip technology allows more and more complex functions to be performed by an increasing number of modules with limited space and power. The deep miniaturisation and cost reduction of such modules has a positive impact on their application areas. They can be used, for example, inside machine tools for dimensional inspection of workpieces or deformation of the tool tip. Modules of this type must contain as many standard components as possible and, in particular, a processing unit responsible, among other things, for processing the optical sensor signal. For this reason, this study reviews and compares algorithms for object edge detection useful in embedded systems based on standard single chips, cores based on Cortex-M4F. The complexity of processing and the quality of algorithm output data was analysed. The results of experimental studies are presented. It was found that the required processing times significantly reduce the use of single chip embedded systems only for edge detection on small images.
The Promising Salt-Stress Reducing Bacteria in Improving Rice Yield in Coastal Area

Decreased rice production due to soil salinity has been widely reported. Alternative promising technologies to overcome this problem is urgently needed. This study aimed to evaluate the ability of salt-stress reducing bacteria to increase rice yield in salt affected areas of low-lying coastal plain. The study consisted of laboratory analyses and field experiment on farmers' land affected by salinity in Indramayu, West Java, conducted in 2018. A total of eight strains of Pseudomonas and Bacillus from previous studies were selected based on their ability to produce ACC (1-aminocyclopropane-1-carboxylate) deaminase and other benefit functional traits. These bacteria were further tested for ethylene emission reduction and exopolysaccharide (EPS) production and formulated into four groups of consortia of salt-stress reducing bacteria (PC1, PC2, PC3 and PC4) based on functional trait combination. Each concortium contains three strains bacteria formulated into peat-based carriers for field experment. Randomized block design with two treatment factors were applied, namely group of concortia bacteria (five levels) and organic fertilizer (two levels), with three replications. Results of the laboratory analyses showed that besides producing ACC deaminase enzyme, fixing N2, and solubilizing fixed phosphates, most of bacterial strains were also able to produce EPS and reduce ethylene emission. Field experiment showed that salt-stress reducing bacteria of PC2 increased rice yield with or without organic fertilizer treatments and hence promising as a saline soil biofertilizer.

What Relation Exists between Corporate Social Responsibility and Longevity of Firms?

The relation between company longevity and its performance is undeniable; however the relationship between sustainability and performance remains the subject of multiple studies which seem to confirm a positive link. But what type of relationship exists between a firm’s longevity and sustainability management? In this paper, we demonstrate that the adoption of corporate social responsibility (CSR) principles explains this link. Therefore, sustainable development policies can create a rampart wall which protects firms against crisis through its three pillars (environmental, social and economic) and thus limit the number of enterprises which go bankrupt. This rampart wall would be even more effective if the principles of sustainable development which companies adopt were guided by a suitable mix of soft law and hard law.

RELATIONSHIP BETWEEN INTERFACE ALERTS AND COMPLACENCY ON HUMAN-AUTOMATION IN-TERACTION: A THEORETHICAL APPROACH

The arrival of automated systems have brought new chalenges to the field of human factios and ergonomics, specially when it comes to the human role on the development of the task. According to Parasuraman & Sheridan (2005), the introduction of automated elements on an environment changes the users’ role, from an operational position to a passive monitor of the system workflow. Within this logic, the user needs to be attentive to sudden changes on the environment and also be capable to identify extreme cases, where he/she might need to interveighn.
An Evaluation of the GamAnalytics Tool: Is the Gamification Analytics Model Ready for Teachers?

In order to improve students’ learning outcomes, researchers and practitioners have increasingly applied gamification in technology-enhanced learning environments. However, some studies in the literature have reported unexpected negative results with that. To avoid these unexpected outcomes in gamified learning systems, we proposed the “gamification analytics model for teachers” in a previous study. This model allows teachers to monitor and adapt the gamification design in the run-time of the teaching-learning process. In this paper, we present the results obtained in an empirical study to assess teachers’ perception and acceptance regarding the GamAnalytics tool, a tool developed based on our proposed model that allows teachers to monitor students’ interaction with learning resources and game elements and adapt tailored missions for students in gamified educational systems. The results indicate that the teachers have significantly good behavioral intention to use our tool and good perception of its usefulness and ease of use. The teachers also indicated enjoyment, relevance, and self-efficacy. Resumo. Para melhorar os resultados de aprendizagem dos alunos, pesquisadores e profissionais têm aplicado cada vez mais a gamificação em ambientes de aprendizagem aprimorados por tecnologia. No entanto, alguns estudos na literatura relataram inesperados resultados negativos. Portanto, para evitar esses resultados inesperados em sistemas de aprendizagem gamificado, propusemos o “modelo de análise de gamificação para professores” em um estudo anterior. Esse modelo permite que os professores monitorem e adaptem o design da gamificação durante o processo de aprendizagem. Neste artigo, apresentamos os resultados obtidos em um estudo empı́rico para avaliar a percepção e aceitação dos professores em relação à ferramenta GamAnalytics, uma ferramenta desenvolvida com base no nosso modelo proposto que permite aos professores monitorar a interação dos alunos com recursos de aprendizagem e elementos de jogo e adaptar missões para estudantes em sistemas educacionais gamificados. Os resultados indicam que os professores têm uma intenção comportamental significativamente boa de usar nossa ferramenta e uma boa percepção de sua utilidade e facilidade de uso. Os professores também indicaram prazer, relevância e autoeficácia.

Gender disparities in poverty among smallholder livestock farmers in South Africa

This paper analyses gender disparities in poverty and the determinants of poverty among smallholder communal livestock farmers across five provinces in South Africa. A combination of multi-stage and stratified sampling techniques were used to select 591 farmers across the provinces. The Foster, Greer and Thorbecke (FGT) poverty indices were used to determine the extent and severity of poverty among smallholder livestock farmers. The results of the FGT analysis revealed that poverty is prevalent among smallholder livestock farmers but more pronounced among female-headed households. A binary logit regression was used to determine the predictors of poverty among communal livestock owners. Factors such as level of education, gender of household head, access to markets and extension services reduce the probability of a household becoming poor. Conversely, factors such as household size and access to credit had a negative effect on household well-being. These results highlight the importance of strengthening institutions (extension, livestock farmer organisations and markets) to improve smallholder livestock systems. Further, the study recommends that agricultural extension services should integrate gender mainstreaming in interventions that target smallholder communal livestock farmers, and that rural development projects should focus on interventions that aim at diversifying farm income.
