Abstract The Eight Disciplines (8D) is a problem-solving technique methodology to identify the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems. 8D is a remarkable first step to enhancing Quality and Reliability when the product is defective or not satisfying the customer. The study was conducted in a manufacturing company producing and assembly wire harness. The data was collected for a period of Three months from July 2020 to September 2020, to identify defective percentage of wire harness and they were found to be high at the average rate of 51.39%. In this work the objective was set to investigates quality issues and provides a solution to reduce the rejection of wiring harness mainly in crimping process. In order to achieve this, 8D problem solving technique was used to analyze and solve the problem. Then, Pareto analysis was done to identify vital causes contributing defectives. From the Pareto analysis, it was found that functioning contact crimp condition with percentage 66.67% is the major cause for rejection. Further brainstorming sessions was held to identify the root causes. After the brainstorming session, cause and effect diagram was constructed and it was found to be variation in the that the connector near cable chain is moving area. Thus, the wire assembly with too high radius may caused external force to the wires when machine running with speed and the end of wire may break off when the wire stretched. The suggestions to reduce the rejection percentage were to install mounting bracket prevent wires shaking when machine running and use proper crimp tools. After implementing the suggestion, the total rejection for wire harness particularly contact crimp condition was reduced to 0.93% in December 2020, from average rejection of 66.67%. (3 months data).

This chapter outlines an optional session for clients with ADHD that focuses on procrastination. It describes how the therapist can discuss the attractive aspects of procrastination and how the client can learn to identify the negative consequences of procrastination. An exercise is presented where the client goes over the pros and cons of procrastination using a specific example. The chapter includes a discussion of how previously taught skills of problem-solving, adaptive thinking, and cognitive restructuring can be applied to procrastination. A case vignette illustrates the process of identifying the long-term and short-term effects of procrastination.

In the actual situation, because of the shock of automobile in the movement process and the wire harness in undulating tube placement is random, leading to the relative position of the wire harness is not fixed, Thus lead to crosstalk value has certain dynamic range. In this paper, obtained the unit mutual inductance and mutual capacitance of wire with insulation layer using mirror image method, simulation and prediction of crosstalk dynamic interval by statistical simulation method, obtain harness near end crosstalk changes range within 3dB at a confidence level of 80%. This provides a reference for EMC design of automotive wiring harness.

Abstract. Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone platforms, satellite images, and historic aerial photographs, we observed the rapid retreat of a permafrost coastline on Qikiqtaruk – Herschel Island, Yukon Territory, in the Canadian Beaufort Sea. This coastline is adjacent to a gravel spit accommodating several culturally significant sites and is the logistical base for the Qikiqtaruk – Herschel Island Territorial Park operations. In this study we sought to (i) assess short-term coastal erosion dynamics over fine temporal resolution, (ii) evaluate short-term shoreline change in the context of long-term observations, and (iii) demonstrate the potential of low-cost lightweight unmanned aerial vehicles (“drones”) to inform coastline studies and management decisions. We resurveyed a 500 m permafrost coastal reach at high temporal frequency (seven surveys over 40 d in 2017). Intra-seasonal shoreline changes were related to meteorological and oceanographic variables to understand controls on intra-seasonal erosion patterns. To put our short-term observations into historical context, we combined our analysis of shoreline positions in 2016 and 2017 with historical observations from 1952, 1970, 2000, and 2011. In just the summer of 2017, we observed coastal retreat of 14.5 m, more than 6 times faster than the long-term average rate of 2.2±0.1 m a−1 (1952–2017). Coastline retreat rates exceeded 1.0±0.1 m d−1 over a single 4 d period. Over 40 d, we estimated removal of ca. 0.96 m3 m−1 d−1. These findings highlight the episodic nature of shoreline change and the important role of storm events, which are poorly understood along permafrost coastlines. We found drone surveys combined with image-based modelling yield fine spatial resolution and accurately geolocated observations that are highly suitable to observe intra-seasonal erosion dynamics in rapidly changing Arctic landscapes.

This paper analyses the microcomputer as a therapeutic tool and discusses its potential use in the treatment of the multiple problems of patients suffering from cerebral vascular accident and head injury. Consideration is given to the theories underlying current treatment approaches in order to evaluate the microcomputer's effectiveness. A problem-solving approach is taken to look at both the short-term and long-term problems that can arise and how this tool can be used to solve them.

The purposes of this case study is to analyze and identify the variation of sewing workers’ performance of the apparel industry with respect to working hours in a day and different working days; and find out possible solutions to overcome these variations. Data was collected following the theory of work study and then statistical hypothesis test such as two-way ANOVA was done to uncover the variations within the work station relative to working hours and working days and the variations were occurred in around 70% work stations whereas 53% stations faced variation in hourly only. Furthermore, the findings were analyzed by Delphi technique with a group of experts to identify the causes and the corresponding solutions. The Delphi experts group used a cause and effect diagram to identify the causes and finally suggested short-term and long-term solutions.

Reflecting Surface

Lagoa dos Patos in southern Brazil is part of the largest lagoonal system in South America. The Holocene lagoonal sediments of the Lagoa dos Patos, mostly muds, have an average thickness of about 6 m as determined by 297 km of 7.0 kHz echograms. Holocene muddy sedimentation developed over a probable Upper Pleistocene coastal plain, whose surface has a subbottom reflector that could not be penetrated by the energy of a 7.0 kHz seismic wave. The characteristics of this reflecting surface suggest indurated Pleistocene muds and/or sediments that are coarser than the overlying muddy deposits of Holocene lagoon. Based on stratigraphic correlation and the local sea level curve, we estimate that Holocene sedimentation started about 8.0 ka ago. This yields an average deposition rate of 0.75 mm/yr. A broadly comparable average rate of 0.52 ± mm/yr was obtained for cored intervals between 14C samples from the upper part of these muddy Holocene lagoon deposits. These long-term sedimentation rates are much slower than rates based on two determinations of 210Pb for surface muds deposits in the last 150 years, which yielded values of 3.5 and 8.3 mm/yr. Quite possibly the high short-term rates may be the result of more rapid lagoonal sedimentation related to deforestation of the watershed of the lagoon and other impact types related with human activities during the 150 years of European colonization in the Rio Grande do Sul state. Also, the aim of this study is to identify present and possible future environmental problems related with high lagoonal sedimentation rates such as the water quality, port dredge and the presence of mud deposits on the oceanic beach.
