Delphi Analysis

World trade has grown over the last two decades and has led to increasing demand for containers. As such, container transport by truck is growing either inside or outside the port terminal. This study aims to gain expert confirmation of the clarity and practicality of the 'congestion problem model in empty container depots' through the Delphi technique. This technique is carried out in two rounds by several experts who have knowledge and experience in container management. Overall, the Delphi analysis shows that the average value exceeds 75%, proving that the model of the congestion problem chain has been approved by the panel of experts. Finally, all panel of experts has the same view regarding the development of this model that it is able to provide a clear understanding of the factors involved in congestion problems outside of the port. Therefore, this model can also serve as a guideline for stakeholders to reduce delays especially during the operation of empty container pick-up and drop-off.

Increasing Demand

Increasing demand for high precision positioning systems has motivated significant research in this field. Within this field, dual-stage nanopositioning systems have the unique potential to offer high-speed and long-range positioning by coupling a short-range, high-speed actuator with a long-range, low-speed actuator. In this paper, design considerations for a spatial filter are presented. The spatial filter allows for control allocation based on range of the signal as opposed to more commonly used frequency-based control allocation. In order to understand the spatial filtering approach more fully, this paper analyzes the filter in detail to understand limitations and give the user a more clear understanding of the approach. Simulation results are included to illustrate aspects of the discussion.

Empty Containers

International trade imbalances make the management of empty containers within shipping networks an important economic and ecological problem. While import-dominated ports accumulate large amounts of empty containers, export-dominated ports need them as transport resources, requiring a repositioning transportation of empty containers on the sea and land side. Acknowledging the importance of the problem, plenty of respective literature has appeared. Since periodic review inventory management systems allow to model the inherent stochasticity of empty container transportation, they have emerged as a major solution approach in the domain. Nevertheless, existing approaches often omit crucial economic and ecological real world conditions determining the success of empty container management. Pollution, repair options, and street-turns are important aspects in this context. In this work, we present new stochastic review policies incorporating a realistic allocation scheme for empty container emissions, realistic maintenance, and repair options as well as street-turns. We analyze the optimality of the proposed polices and evaluate them in a simulation model with metaheuristic parameter search based on extensive real-world data from a major global shipping company operating in Latin America. Results provide insights for academics and practitioners about the economic and ecological impact of the distinct empty container management polices within a shipping network.

Abstract Background: This study was aimed to improve the information adequacy of clinical Morning Reports by developing a structured reporting model. Methods: This study was a qualitative research conducted in three phases at the Obstetrics and Gynecology Department of three educational hospitals in northeastern Iran. After investigating the current status of MR sessions, the content of 120 reports were included extracted. The items were assigned subject groups for primary structuring while their validation getting confirmation using a two-round Delphi technique involving 10 specialists. Then, the structured model of clinical MRs was developed in two formats: structured paper-based form (SPF) and structured electronic format (SEF). The final evaluation was conducted comparing three practices of SPF, SEF, and conventional formats.Results: All studied MR samples were found unstructured in content. From 120 collected samples, 58 items were extracted and categorized into four categories. During the first Delphi round, all existing information were preserved with varying weights. but the participating experts also suggested six additional items to be included. In the second round, 11 items with the lowest scores were removed. Results of the comparative evaluation showed that the SPF format scored highest on the preference of use, ease of archiving and retrieval, application in future research, and ease of reporting. The SEF format scored highest on the clear understanding of patient status and readability.Conclusion: Using a standardized structured morning report based on the preference of local experts improves the quality of morning reports in various matters including efficiency, adequacy, and ease.

Progressive development in the industrial field leads to the increasing demand for superalloys with enhanced mechanical properties, such as toughness, hardness, ductility, damping strength, tensile strength and improved surface finish. Monel 400, one of such superalloys, with the majority of its application in aerospace and marine fields demands a good super finish. There arises the need for some nonconventional processes like WEDM. This process is more effective to obtain complex shapes to close tolerance. This research focuses on clear understanding of the machining strategies with proper parametric combinations to achieve an improved surface finish, subsequently reducing the time and expense involved in the superfinishing procedure. The surface qualities of the selected samples are validated with the help of roughness profile and topography images. This study has proven that the increasing input current and wire feed rate (WFR) consistently decreases the surface roughness (SR; [Formula: see text] of the specimen. This paper also explains the effect of topographic parameters and microstructure over the resulting SR. In addition, the consistent contribution of WFR and input current toward the lower SR is established. The relationship between morphological behavior and parametric deviations is evaluated. A significant correlation found to exist between the rate of wire feed and the height parameters of SR such as [Formula: see text], [Formula: see text], etc.

Cattle  farm  agribusiness  in  Indonesia  is  still  a  sector  that  needs  to  be developed,  given  the  increasing  demand  for  meat,  but  has  not  met  from  domestic meat  production.  One  of  the  efforts  to  achieve  stability  availability  of  beef  that  is through  an  increase  in  beef  cattle  fattening  which  have  long-term  prospects.  This study  aims  to  identify  and  analyze  the  financial  benefits  fattening  beef  cattle  in Bojonegoro  which  is  one  of  the  central  areas  of  the  cow  kind  Peranakan  Ongole (PO)  in  the  province  of  East  Java.  Data  were  analyzed  quantitatively  by  using indicators  of  profitability  and  feasibility  ie  B  /  C  Ratio,  Break  Even  Point,  Net Present Value, Internal Rate of Return, and Payback Period. The research location in  the  village  Napis,  District  Tambakrejo  with  30  respondents  breeders  who  do fattening for 4 months. The results showed the average value of B / C ratio of 1.23, NPV of USD 481 110, 59, IRR 11.30%, and PBP for 2 years and 9 months. Based on the research results can be suggested to the Government of Bojonegoro in order to provide  guidance  and  directs  farmers  to  conduct  fattening  cattle  given  the  small number of farmers who cultivate the cow on a large scale.
