Warehouse Operations

This article examines the current state of warehouse logistics, which is characterized by the use of automated technologies and software for work performed in the warehouse to reduce logistics costs. Automation of all types of warehouses increases the cost of warehouse operations by automating small, repetitive tasks, allowing workers to focus on more complex tasks. The development of information technologies and the use of modern technology expand the possibilities of improving the efficiency of the warehouse. The warehouse robotics industry includes several types of warehouse robots that serve different purposes and functions, such as filling orders and moving inventory in a warehouse, etc. One of the types of warehouse robotics that we consider in this article are vehicles with automatic control technology AGV (Automatic guided vehicle). The AGV technology is based on an automatic trolley, an electric tool that transports goods from place to place. Since the trolley is controlled automatically, maintenance of the trolley does not require a separate operator-the trolleys move along a given trajectory in isolated conditions without the need for human labor. In addition to the need to maintain the required product quality, the use of AGV has the following advantages: reducing the number of personnel, especially high-quality and responsible transport operators, ensuring occupational safety, minimizing damage caused by product damage, since all movements of vehicles with automatic control can be precisely programmed.

The study was conducted among 104 mango producer through primary data collection to assess the profitability in mango production, demographic and socio-economic condition of farmers in four villages of Northern region of Bangladesh. The study encompasses the comparison of cost and profit of other crop with mango cultivation. Most farmers depend on mango production because the climate is unfavorable for field crop production but very conducive for mango cultivation in Barind ecosystem. Problem Confrontation Index (PCI) was used to measure the problems of mango production. On the basis of PCI formula, out of the 16 problems, insects and diseases infestation was identified as the major problem with PCI 429 followed by dropping of fruits and flowers with PCI 409. Lack of better varieties/ Seedling/ grafts, modern technology and climate change was also three major problems with PCI 387, 193 and 276 respectively. Cost and return analysis of mango production revealed that 10 mango varieties are founds as profitable with the higher working investment and human labor development. Cultivator had to spend 106659 taka for one hectors of land or 120 mango trees and average profit was 299010. Average profit from mango cultivation (299010Tk/ha) was higher than Average profit from onion cultivation (260412Tk/ha).Most farmers (about 87%) practiced intercropping with mango. the cost incurred by Harvesting, Sorting and Grading of mango cultivation was more than other crops. Although respondents certified that Rajshahi district is profitable in respect of mango production further study should be taken place with other variables and characteristics. Res. Agric., Livest.

Pulp Production

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.

The Russian Language

The article considers the current state of the Russian language. Information technologies in the twenty first century present diverse forms of linguistic knowledge and modalities of knowledge quantisation in a linguistic sign. The Russian language develops from a standard, direct expression of thoughts to a nonstandard, psychologically complex, associative deep statement of thoughts. In the early nineteenth century, during the democratisation of the Russian language, a national genius, Alexander Pushkin, emerged. Thanks to him, the unique informational, cultural, and artistic evolution of the language took place. Nowadays, while democratisation and globalisation, processes which resemble the language evolution 200 years ago, are occurring. These processes suggest some patterns: overcoming stylistic disparity, changes in linguistic sign boundaries and semantic extension.

CAR-T (chimeric antigen receptor T) cells have emerged as a milestone in the treatment of patients with refractory B-cell neoplasms. However, despite having unprecedented efficacy against hematological malignancies, the treatment is far from flawless. Its greatest drawbacks arise from a challenging and expensive production process, strict patient eligibility criteria and serious toxicity profile. One possible solution, supported by robust research, is the replacement of T lymphocytes with NK cells for CAR expression. NK cells seem to be an attractive vehicle for CAR expression as they can be derived from multiple sources and safely infused regardless of donor–patient matching, which greatly reduces the cost of the treatment. CAR-NK cells are known to be effective against hematological malignancies, and a growing number of preclinical findings indicate that they have activity against non-hematological neoplasms. Here, we present a thorough overview of the current state of knowledge regarding the use of CAR-NK cells in treating various solid tumors.

The Ideal

In the current state of the art, WiFi-alike standards require achieving a high Image Rejection Ratio (IRR) while having low power consumption. Thus, quadrature structures based on passive ring mixers offer an attractive and widely used solution, as they can achieve a high IRR while being a passive block. However, it is not easy for the designer to know when a simple quadrature scheme is enough and when they should aim for a double quadrature structure approach, as the latter can improve the performance at the cost of requiring more area and complexity. This study focuses on the IRR, which crucially depends on the symmetry between the I and Q branches. Non-idealities (component mismatches, parasitics, etc.) will degrade the ideal balance by affecting the mixer and/or following/previous stages. This paper analyses the effect of imbalances, providing the constraints for obtaining a 40 dB IRR in the case of a conversion from a one-hundred-megahertz signal to the five-gigahertz range (upconversion) and vice versa (downconversion) for simple and double quadrature schemes. All simulations were carried out with complete device models from 65 nm standard CMOS technology and also a post-layout Monte Carlo analysis was included for mismatch analysis. The final section includes guidelines to help designers choose the most adequate scheme for each case.

Principal Component Analysis (PCA) is a classical dimensionality reduction technique that computes a low rank representation of the data. Recent studies have shown how to compute this low rank representation from most of the data, excluding a small amount of outlier data. We show how to convert this problem into graph search, and describe an algorithm that solves this problem optimally by applying a variant of the A* algorithm to search for the outliers. The results obtained by our algorithm are optimal in terms of accuracy, and are shown to be more accurate than results obtained by the current state-of-the- art algorithms which are shown not to be optimal. This comes at the cost of running time, which is typically slower than the current state of the art. We also describe a related variant of the A* algorithm that runs much faster than the optimal variant and produces a solution that is guaranteed to be near the optimal. This variant is shown experimentally to be more accurate than the current state-of-the-art and has a comparable running time.
