Abstract:

A process improvement of incoming inspection for the materials used by a steelmaking enterprise is explained in this paper. The applied methods were described with examples considering the need of the improved process. The process complexity is explained in turn by the existence of the involved actors that need to exchange information about the inspected materials. The results obtained by the improved process justify the action started in 2012 for the incoming inspection process by a more constant quality level of the materials, reduction of the overall process duration, better materials information exchange and a convenient method for supplier surveillance and evaluation.

Abstract:

Abstract Reinforcement learning is the most preferred algorithms for optimization problems in industrial automation. Model-free reinforcement learning algorithms optimize for rewards without the knowledge of the environmental dynamics and require less computation. Regulating the quality of the raw materials in the inbound inventory can improve the manufacturing process. In this paper, the raw materials arriving at the incoming inspection process are categorized and labeled based on their quality through the path traveled. A model-free temporal difference learning approach is used to predict the acceptance and rejection path of raw materials in the incoming inspection process. The algorithm presented eight routes paths that the raw materials could travel. Four pathways correspond to material acceptance, while the rest lead to material refusal. The materials are annotated using the total scores acquired in the incoming inspection process. The materials traveling on the ideal path (path A) get the highest total score. The rest of the accepted materials in the acceptance path have a 7.37% lower score in path B, whereas path C and path D get 37.28% and 42.44% lower than the ideal approach.

Abstract:

The cell characterization in the incoming inspection is an important but time and cost intensive process step. In order to obtain reliable parameters to evaluate and classify the cells, it is essential to design the test procedures in such a way that the parameters derived from the data allow the required statements about the cells. Before the focus is placed on the evaluation of cell properties, it is therefore necessary to design the test procedures appropriately. In the scope of the investigations two differently designed incoming inspection routines were carried out on 230 commercial lithium-ion battery cells (LIBs) with the aim of deriving recommendations for optimal test procedures. The derived parameters of the test strategies were compared and statistically evaluated. Subsequently, key figures for the classification were identified. As a conclusion, the capacity was confirmed as an already known important parameter and the average cell voltage was identified as a possibility to replace the usually used internal resistance. With regard to capacity, the integration of CV steps in the discharging processes enables the determination independently from the C-rate. For the average voltage cycles with high C-rates are particularly meaningful because of the significant higher scattering due to the overvoltage parts.

Abstract:

A letter is a means to submit a statement or information in writing from one party to another. The information may be a notice, statement, request, report, thought, rebuttal and so on. The management of letters within an institution is categorized into two, namely incoming and outgoing mail. An incoming letter is a letter received by an organization / institution made by another official organization / institution and an outgoing letter is a letter sent by an organization / institution made by another official organization / institution. BRI Inspection Office is representative of BRI directors in regions that perform supervisory function of operational working units in the region, or it can be said is the eyes and ears of directors in the region. Including the Inspection Office of BRI Padang City, which oversees the operational work units located in the Padang City area and conducts audits with the aim of ensuring that internal controls in the operational work units in their working areas are effective especially in Padang City. In the mail archiving system, there are many piles of unorganized letters so that when supervisors want to check incoming mail or outgoing mails they will not be properly managed. This new letter governance information system is expected to make it easier for the BRI Inspection Office to manage the archiving of incoming and outgoing mail.

Abstract:

Abstract The incoming inspection process in any manufacturing plant aims to control quality, reduce manufacturing costs, eliminate scrap, and process failure downtime due to defective raw materials. Prediction of the raw material acceptance rate can regulate the raw material supplier selection and improve the manufacturing process by filtering out non-conformities. This paper presents a raw material acceptance prediction model (RMAP) developed based on the Markov analysis. RFID tags are used to track the parts throughout the process. A secondary dataset can be derived from the raw RFID data. In this study, a dataset is simulated to reflect a typical incoming inspection process consisting of six substations (Packaging Inspection, Visual Inspection, Gauge Inspection, Rework1, and Rework2) are considered. The accepted parts are forwarded to the Pack and Store station and stored in the warehouse. The non-conforming parts are returned to the supplier. The proposed RMAP model estimates the probability of the raw material being accepted or rejected at each inspection station. The proposed model is evaluated using three test cases: case A (lower conformities), case B (higher conformities) and case C (equal chances of being accepted and rejected). Based on the outcome of the limiting matrix for the three test cases, the results are discussed. The steady-state matrix forecasts the probability of the raw material in a random state. This prediction and forecasting ability of the proposed model enables the industries to save time and cost.

Abstract Reinforcement learning is one of the promising approaches for operations research problems. The incoming inspection process in any manufacturing plant aims to control quality, reduce manufacturing costs, eliminate scrap, and process failure downtimes due to non-conforming raw materials. Prediction of the raw material acceptance rate can regulate the raw material supplier selection and improve the manufacturing process by filtering out non-conformities. This paper presents a Markov model developed to estimate the probability of the raw material being accepted or rejected in an incoming inspection environment. The proposed forecasting model is further optimized for efficiency using the two reinforcement learning algorithms (dynamic programming and temporal differencing). The results of the two optimized models are compared, and the findings are discussed.

Abstract:

Consistent with the precepts of total quality control and total quality management, there has been a resource shift from incoming and outgoing inspection processes to statistical quality control of processes. Furthermore, process control operators are responsible for their own quality, necessitating the in-process inspection of components. This study treated the statistical process control task of “searching” control charts for out-of-control conditions as an inspection task and applied the Theory of Signal Detection to better understand this behavior and improve performance. Twelve subjects participated in a research study to examine how the portrayal of control chart information affected signal detection theory measures. The type of display did not have a significant effect on the sensitivity and response criterion of subjects. These results are discussed in terms of the applicability of Signal Detection Theory in control chart decision making as well as implications on display design.

Abstract:

There is a great need for an in-line, high-speed and non-destructive inspection system capable of evaluating and analyzing the quality of SiC wafers for SiC power devices. We have examined whether the laser-based optical non-destructive inspection system by KLA-Tencor meets these requirements. Using this system, incoming inspection of purchased SiC wafers has been performed. The obtained inspection data show that micropipe density is sufficiently low in a device-grade wafer, and therefore, micropipes are not the main cause of device failure. The next challenges for a device-grade SiC wafer are reduction of epitaxial defects and relatively small defects classified as “particles”.

Abstract:

A study into the failure causes of mixing and charging equipment confirms that the main impact on the probability of accidents is the use of raw materials that do not meet the specifications and have unstable properties. The raw materials used for explosives preparation in mechanized charging of boreholes include such components as ammonium nitrate, emulsion phase, diesel fuel, emulsifier and others. The paper describes the application of various formulations with these components in specific types of mixing and charging machines manufactured by AZOTTECH LLC. The main properties that affect the quality of raw materials are summarised, and the incoming inspection of explosive components is described as part of the acceptance procedure at temporary storage sites at a hazardous production facility. The paper describes common types of equipment failures and maintenance procedures when using substandard raw materials. The conclusion highlights the key practices to improve the equipment uptime as well as recommendations for incoming inspection and the use of high-quality explosive components.

Abstract:

Si l icon car b ide (Si C ) man u f act u ring is transitioning from 4 inch wafers to 6 inch wafers for production line devices. The main obstacle for SiC manufacturing high yield is defect control. Defectiveness inline control is well established for silicon power device. However, there are two main challenges related to SiC technology. The first challenge is incoming 4H-SiC substrates defectivity and epi layer crystallographic defects. The second challenge is inline defect detection at process steps such as implantation and annealing activation [,]. Defect detection and classification are difficult with current defect inspection tools because of substrate transparency at visible light, color variation, roughness, and wafers’ high warpage. In addition, SiC device integration has been requesting specific optimization. In this paper, collaboration studies have been done to develop solutions to these challenges. Yield correlation analyses have validated the process control flow set to address these two major challenges and to enable the fast ramp of the 6” production line of SiC devices.

Abstract:

In connexion with the rapidly growing computer network information capacities, information security of local networks connected with global networks becomes a critical challenge. One of the information security aspects is to control and filter the network traffic by intercepting the incoming and outgoing network packets. This is accomplished owing to firewalls. The Linux kernel 2.4.x included the Netfilter firewall and the iptables utility, which allow us to analyse only the packets headers and their pertaining to specific network connections. In addition, the practice of rewriting the Linux kernel codes complicates the maintenance of the software targeting for this firewall.The article proposes a network packet intercepting method based directly on the structures and functions of the kernel, so it has no restrictions associated with the inherent Netfilter/iptables functionality. To provide intercepting, are used the struct net_device structure of the kernel that describes a network device and the struct net_device_ops structure that lists operations possible on the network device and two functions: ndo_start_xmit and rx_handler used to process outgoing and incoming packets, respectively. These functions are rewritten in order to include new functionality into the kernel to meet the users’ requests. The use of the structures and functions of the kernel provides desirable stability, versatility, and adaptive capability of the developed software for users’ requests such as content analysis of data transmitted in packets, their encryption and decryption. The proposed method can be used to create firewalls of the next-generation to implement technology of deep packet inspection, as well as a complement to the available firewalls.

Abstract:

Testing is necessary to verify that very large scale integration ICs (VLSI-ICs) conform to their specifications. This can grow from a more or less reduced incoming inspection test to a full qualification test consisting of a characterization, environmental tests, reliability tests, and failure analysis. The aim of a screening is to eliminate weak ICs that would cause early failures. This article presents the possibilities and limits of testing and screening very large scale integration ICs (VLSI-ICs). Practical results are given, and the procedures for the qualification of these ICs are discussed. The concept of test strategy is introduced, and the question of the choice between 100 percent and sampling inspection test is answered.

Abstract This article contains substantiation of the improvement of inspection instruments used for the repairs of farming machinery during incoming quality inspection, in-process inspection, and acceptance testing. The design of a gauge plug has been developed for repairs and with the purpose of inspection of bushing bores of the intermediary shaft bearing with the diameter of Ø48.8F7 for ZMZ engines. The manufacturing tolerance for go-side and no-go side has been determined. The deviation of the middle of the tolerance range in relation to the smallest limiting size of the gauge plug was 3.5 μm. The permissible overrun of a worn-out of the gogauge outside of the tolerance range border was – 3 μm. The manufacturing tolerance for the size of the check caliper gauge has also been determined and limiting dimensions of the check gauge have been calculated. Taking into account the values derived a layout for the gauge plug tolerance range has been developed in order to inspect the bushing bores of the intermediary shaft bearing with the diameter of Ø48,8+0,050 +0,0025.

Abstract:

The use of FRP (also known as RTP—reinforced thermoset plastic) in chemical process service has grown rapidly since introduction due to its unique corrosion-resistant properties and cost effectiveness. There have been some failures due to inadequate specifications, poor design or improper fabrication. An ASME Committee was formed to provide a standard and ASME/ANSI RTP-1 “Reinforced Thermoset Plastic Corrosion Resistant Equipment” was approved as an American National Standards Institute (ANSI) Standard in March 1989. The Standard applies to stationary vessels operating at pressures not exceeding 15 psig external and/or 15 psig internal above any hydrostatic head. This article describes the detailed specification process, the methods for design and fabrication, material requirements, procedures for qualification of a shop and its personnel, the fabricator’s Quality Control Program, and inspection and testing required by the Standard. It is recognized that there will be significant costs associated with fabrication of vessels to this standard. The careful preparation of the specifications, the conservative approach to design, the qualification of the Fabricator’s shop and personnel, the inspection of incoming raw materials, the inspection and testing of the finished vessel and the services of the mutually acceptable Inspector are all cost items. Balancing these costs will be the benefits of improved safety and reliability, long life, low maintenance, and hopefully less litigation and liability. It is believed that, on an overall long-term cost basis, these benefits will far outweigh the added costs.

Full text

Abstract:

Abstract For high-reliability microelectronics with uses in aerospace, defense, automotive, and medical applications, in-line visual inspection during the die sort process allows for a higher quality and more robust process for generating known-good-die. The visual inspection serves three primary functions: verifying unique device characteristics (such as bumps, MEMS structures, waveguides, etc.), verifying the device is free from singulation defects, and verifying the die sort process induces no device damage. Performing a visual inspection of the die top surface and one edge during the pick and place process allowed qualification of a non-surface contact edge grip approach for sensitive surface MEMS and optoelectronic parts. Die 100 microns thick or less were also inspected to ensure no cracking during the die pick process. For continual process reliability improvement and optimization, the inspection results must be captured and logged along with incoming product details including the wafer ID, electrical test results, and chip ID. This logged information is then traceable to the die position in the output medium. As new device manufacturing technology is implemented, this screening for process-induced defects is required for a robust manufacturing process.

Abstract:

This paper describes a transportable spectrophotometer system developed for real-time classification of poultry carcasses on-site at slaughter plants. The system measures the spectral reflectance of poultry carcasses in the visible/near-infrared regions (471 to 963.7 nm). An optimal neural network classifier for real-time classification of poultry carcasses into normal, septicemic, and cadaver classes with an average accuracy of 93% was obtained. When the classifier was used to classify the carcasses into two classes, normal and abnormal (septicemic and cadaver), the average accuracy was 97.4%. The percentages of the false positive and the false negative error rates were 2.4 and 2.9%, respectively. This paper also proposes implementing the system at the slaughter plants as a poultry carcass screening system (PCSS). Using two visible/NIR spectrophotometer systems, the PCSS tests both sides of the breast of each bird. With the PCSS, the inspection-passed-bird and inspection-rejected-bird error rates by the spectrophotometer systems would be minimal, and less than 5% of the incoming birds would require further inspection by human inspectors.

Abstract:

A key component of the quality management system is the incoming quality control of raw materials, materials and components. The course of the further production process and the quality of manufactured products depend on the correctness of its implementation, the accuracy of compliance with all the necessary procedures. Another important aspect that is inextricably linked with incoming inspection is working with suppliers. In order to minimize costs and increase the effectiveness of actions, it is necessary to establish a stable and well-coordinated work on the supply of raw materials, materials and components. To accomplish this task, the enterprise must develop and approve a methodology for evaluating suppliers, which allows them to conduct a comprehensive analysis, choose the most reliable suppliers with a proven reputation and high performance. The research base is a machine-building enterprise – public joint-stock company “NEFAZ” (PJSC “NEFAZ”). The article identifies problem areas and suggests methods for their improvement. Based on the results of the study, a comprehensive methodology for assessing suppliers has been developed, which makes it possible to determine the rating of the supplier and, depending on this, to establish the type of incoming control. Possible types of effect from the introduction of this technique at the enterprise are considered.

Abstract:

AbstractThe post-mortem inspection of domestic pigs within the European Union was revised in 2014, primarily to include visual meat inspection of each carcase and offal. Palpations and incisions were removed from routine meat inspection procedures, as they are mostly used to detect pathological lesions caused by organisms irrelevant for public health, and instead can cause cross-contamination of carcases with foodborne pathogens. However, examination of all external surfaces of the carcase and organs, declaration of patho-physiological lesions as unfit for human consumption, and possibility for minimal handling of carcases and offals were held in place. In addition, the European Food Safety Authority suggested that palpation and incisions should be performed outside the slaughter line, but this was not incorporated in the revised legislation. We surveyed in 2014 the opinions of meat inspectors and veterinarians using an online questionnaire to determine what practical measures are required for the visual meat inspection procedure and when meat inspection staff consider additional palpations and incisions necessary. Based on the survey, turning the carcase and organs or technical arrangements such as mirrors were seen necessary to view all external surfaces. In addition, the pluck set cannot be trimmed on the side line. Local lesions, such as abscesses and lesions in the lymph nodes, signs of systemic infection and lymphoma, were the major lesions requiring additional post-mortem meat inspection procedures. Meat inspection personnel raised concerns on the poor quality of food chain information and export requirements demanding palpations and incisions. The efficient use of visual meat inspection requires legislation to better support the implementation and application of it, changes in the slaughter line layout and a possibility to classify incoming pig batches based on their risk.

Abstract:

Purpose – As the complexity of the multi-component products increases the quality of these products becomes increasingly difficult to control throughout the supply chain. The first step to manufacturing a quality product is to ensure that the product components from suppliers meet specifications. Product quality can be controlled through sampling inspection of the components. The paper aims to discuss these issues. Design/methodology/approach – The model presented in this paper was developed to determine the optimal sampling levels for incoming lots containing parts for production and assembly of multi-component systems. The main objective of the model is to minimize the expected cost that is associated with a nonconforming item reaching assembly. Findings – In this research, the results showed that even with limited time available for inspection, performing sampling inspection significantly reduced the expected cost of a nonconforming item reaching assembly. The model, solved by the evolutionary algorithm, was able to provide a meaningful, near optimal solution to the problem. Originality/value – In this model the time available for inspection is limited, the distribution of defects is assumed to follow the binomial distribution, and the distribution of accepting the lot with defects follows the hypergeometric distribution. In addition, the inspection is considered to be accurate and, if a nonconforming item is found in the inspected sample, the entire lot is rejected. An example is given with real world data and the results are discussed as they relate to supply chain management and quality.

Abstract:

Abstract Choosing a proper lighting approach is a crucial task in designing visual inspection systems. It becomes especially challenging for complex-shaped, transparent objects, which change the directional distribution of incoming light in various ways. We overcome this challenge by constructing a light field display and deploy it as a highly tunable lighting device. Thereby, an object-specific light field can be generated, which highlights the features of the object under test with maximum contrast. We explain the calibration procedure, the rendering pipeline and present examples of customized illuminations.

Abstract:

This paper studies how to design a mechanism to control the quality of final product and components. Considering that ATO supply chain is composed of multiple component suppliers and a manufacturer, which is the core company and uses incoming inspection and quality tracing to control the quality of components, we presented a quality control model of ATO supply chain and obtain the optimal quality control mechanism consisting of component purchase prices, penalties on defect. We find that the manufacturer will choose the optimal quality level of ATO supply chain; the manufacturer can stimulate suppliers to choose the optimal quality levels of ATO supply chain through designing a reasonable purchase prices and penalties when their reservation payoffs are small, otherwise, it will design a profit transfer mechanism to modify the quality control mechanism, as a result, suppliers will choose the optimal quality levels and the manufacturer’s profit will be maximized.

Abstract:

The removal of plastic contamination in cotton lint is an issue of top priority to the U.S. cotton industry. One of the main sources of plastic contamination showing up in marketable cotton bales, at the U.S. Department of Agriculture’s classing office, is plastic from the module wrap used to wrap cotton modules produced by the new John Deere round module harvesters. Despite diligent efforts by cotton ginning personnel to remove all plastic encountered during unwrapping of the seed cotton modules, plastic still finds a way into the cotton gin’s processing system. To help mitigate plastic contamination at the gin; an inspection system was developed that utilized low-cost color cameras to see plastic on the module feeder’s dispersing cylinders, that are normally hidden from view by the incoming feed of cotton modules. This technical note presents the design of an automated intelligent machine-vision guided cotton module-feeder inspection system. The system includes a machine-learning program that automatically detects plastic contamination in order to alert the cotton gin personnel as to the presence of plastic contamination on the module feeder’s dispersing cylinders. The system was tested throughout the entire 2019 cotton ginning season at two commercial cotton gins and at one gin in the 2018 ginning season. This note describes the over-all system and mechanical design and provides an over-view and coverage of key relevant issues. Included as an attachment to this technical note are all the mechanical engineering design files as well as the bill-of-materials part source list. A discussion of the observational impact the system had on reduction of plastic contamination is also addressed.

Abstract:

Commercial shipping is the primary pathway of introduction for aquatic nonindigenous species (NIS), mainly through the mechanisms of ballast water and biofouling. In response to this threat, regulatory programs have been established across the globe to regulate and monitor commercial merchant and passenger vessels to assess compliance with local requirements to reduce the likelihood of NIS introductions. Resource limitations often determine the inspection efforts applied by these regulatory agencies to reduce NIS introductions. We present a simple and adaptable model that prioritizes vessel arrivals for inspection using proxies for potential propagule pressure (PPP), namely a ships’ wetted surface area as a proxy for the likelihood of biofouling-mediated PPP and ballast water discharge volume as a proxy for ballast water-mediated PPP. We used a California-specific dataset of vessels that arrived at California ports between 2015 and 2018 to test the proposed model and demonstrate how a finite set of inspection resources can be applied to target vessels with the greatest PPP. The proposed tool is adaptable by jurisdiction, scalable to different segments of the vessel population, adjustable based on the vector of interest, and versatile because it allows combined or separate analyses of the PPP components. The approach can be adopted in any jurisdiction across the globe, especially jurisdictions without access to, or authority to collect, risk profiling data or direct measurements for all incoming vessel arrivals.

Abstract:

Product sequencing is one way to reduce cost and improve product quality for multistage manufacturing systems (MMS). However, systematically evaluating the influence of product sequence on quality performance for MMS is still a challenge. By considering the rate of incoming conforming product, manufacturing system quality transition between batch to batch, and quality propagation along stages, this paper investigates the appropriate batch policies and product sequencing for MMS so that satisfied quality performance can be achieved. A model to analyze the relationship between the product sequencing and quality performance is conducted just by using the quality inspection data and the complex engineering knowledge used in the variation method is avoided. Based on Markov Chain processes methodology, quality performance is modeled as a function of transition states jointly determined by multistage condition, product sequencing, incoming part quality, and propagation of the rate of conforming products among multistage. Quality related batch strategies are discussed for optimal quality performance. Two kinds of quality efficiency are put forward to facilitate the modeling and the discussion. The results of the model will lead to guidelines for quality management in multistage manufacturing systems.

Abstract:

The presence of minor compounds in virgin olive oils has been proven to play multiple positive roles in health protection, encouraging its production. The key factors that influence the oil quality are ripening stages and the state of health of the fruit. For this reason, at the oil mill’s reception yard, fruits are visually inspected and separated according to their external appearance. In this way, the process parameters can be better adjusted to improve the quantity and/or quality of olive oil. This paper presents a proposal to automatically determine the oil quality before being produced from a previous inspection of the incoming fruits. Expert assessment of the fruit conditions guided the image processing. The proposal has been validated through the analysis of 74 batches of olives coming from an oil mill. Best correlation results between the image processing and the analytical data were found in the acidity index, peroxide values, ethyl ester, polyphenols, chlorophylls, and carotenoids.

Abstract:

Standards that generally must be owned by companies in order to achieve a good management system are ISO 9001 international standards, these standards govern the company's quality management system. PT XYZ is a printing company, this company has obtained the ISO 9001 certification version in 2008. However, there are the latest developments where in September 2015, ISO issued the latest revised standard so that the ISO 9001: 2008 standard is no longer valid. Therefore, PT XYZ is obliged to migrate or change its standards following the latest revised standard requirements, namely ISO 9001:2015 no later than 2018. The method of risk management analysis is carried out by entering identified risks into the risk management form. Furthermore, the risk of failure and its effect is determined by two factors, namely: the magnitude of the impact if a failure occurs, the second is the probability and frequency of failure. After the classification is carried out, the weighting calculation is performed for all identified risks (risk assessment). Identified risks and their weights are entered into the risk register according to priority, where the risk with the highest weight is placed in the top position. Based on the results of high-risk research (H), namely the production process inspection process and the final inspection QC process. For medium risks, there are 3, namely the process of making COAs, the Incoming Material Inspection process, and the process of handling complaints.

Abstract:

The problem of load balancing in intrusion detection systems is considered in this paper. The analysis of existing problems of load balancing and modern methods of their solution are carried out. Types of intrusion detection systems and their description are given. A description of the intrusion detection system, its location, and the functioning of its elements in the computer system are provided. Comparative analysis of load balancing methods based on packet inspection and service time calculation is performed. An analysis of the causes of load imbalance in the intrusion detection system elements and the effects of load imbalance is also presented. A model of a network intrusion detection system based on packet signature analysis is presented. This paper describes the multifractal properties of traffic. Based on the analysis of intrusion detection systems, multifractal traffic properties and load balancing problem, the method of balancing is proposed, which is based on the funcsioning of the intrusion detection system elements and analysis of multifractal properties of incoming traffic. The proposed method takes into account the time of deep packet inspection required to compare a packet with signatures, which is calculated based on the calculation of the information flow multifractality degree. Load balancing rules are generated by the estimated average time of deep packet inspection and traffic multifractal parameters. This paper presents the simulation results of the proposed load balancing method compared to the standard method. It is shown that the load balancing method proposed in this paper provides for a uniform load distribution at the intrusion detection system elements. This allows for high speed and accuracy of intrusion detection with high-quality multifractal load balancing.

Abstract:

The introduction of non-indigenous aquatic species (NIASs) was identified as one of the major threats to aquatic ecosystems. Shipping is one of the potential invasive pathways for the introduction of marine NIASs, mainly via ballast water, sediments, and ship fouling. In addition, The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM Convention) aims to mitigate the introduction risk of harmful aquatic organisms and pathogens (HAOPs) via ships’ ballast water and sediment. Some of these species can be very harmful and cause loss of biodiversity, adverse environmental consequences, and economic and social impacts. In this study, an empirical model based on the environmental similarity and the vessel characteristics was used to assess the risk associated with the ballast water, for the incoming vessels to the port of Kaohsiung and port of Riga. The priority for port state control (PSC) inspection was established and recommended for better ballast water management.

Abstract:

Abstract With the rapid development of computer technology, sensor technology, and communication technology, people have gradually designed and continuously improved the health monitoring system of bridge structure. Due to the uninterrupted long-term work of the bridge monitoring system, the long-term operation of a large number of sensors will generate massive amounts of data, and a lot of data to be transmitted from the data collector at the bridge site to the data monitoring center requires the use of a wireless network with limited speed, which will consume a lot of time, thereby bring such negative effects as reducing transmission efficiency, reducing throughput, increasing transmission costs, and affecting the entire bridge inspection system. This paper proposes a parallel compression method of LZSS data based on FPGA, which can compress the incoming data from the sensor system in parallel in the data acquisition system to improve the transmission efficiency, increase the throughput, and reduce the transmission cost.

Abstract:

Natural sun-dried raisins are susceptible to crop loss and quality reduction when rainfall occurs during the 2-3 week drying period. The purpose of this experiment was to determine the effect of rainfall at selected stages of the raisin drying period on raisin quality. Thompson Seedless grapes were harvested and dried in the field using normal commercial practices. Raisins were moved to a humid chamber at the green, brown, turn, and roll stages of the drying period. Then, raisins were misted with 6.4 or 25.4 mm of water to simulate rainfall. Samples remained under humid conditions for approximately 48 hours after which they were returned to the field to complete the drying process. Raisin quality was evaluated by USDA incoming inspection procedures. The amount of rainfall had little effect on raisin quality at the levels in this experiment. However, raisin quality was significantly reduced when rainfall occurred at the green and brown stage of drying. Raisins which received rainfall at the turn and roll stages of drying were of comparable quality as control raisins.

Abstract:

Purpose – The purpose of this paper is to present a structured way for the definitions of the Process Failure Mode and Effect Analysis (FMEA) attributes, such as potential failure mode, potential cause and potential effect, in order to make it simpler to define the controls and scores. Design/methodology/approach – This study performs, through a case study in incoming inspection of raw material, the comparison of a conventional application of the Process FMEA with a proposal based on the concepts of process approach defined by ISO 9001. Findings – Even written in a form similar to a script, the application of Process FMEA is a very complex activity and, like most quality tools, before being applied, FMEA should be clearly understood by the team. One way to facilitate this understanding is considering the sequence of events in the failures analysis to understand their causes and effects, just as are the sequences of inputs and outputs in the definition of the process approach addressed in ISO 9001. Originality/value – This paper shows a simple way to better structure Process FMEA, facilitating meetings with multidisciplinary teams.
