Will We Hit a Wall? Forecasting Bottlenecks to Whole Brain Emulation Development

Abstract

Whole brain emulation (WBE) is the possible replication of human brain dynamics that reproduces human behavior. If created, WBE would have significant impact on human society, and forecasts frequently place WBE as arriving within a century. However, WBE would be a complex technology with a complex network of prerequisite technologies. Most forecasts only consider a fraction of this technology network. The unconsidered portions of the network may contain bottlenecks, which are slowly-developing technologies that would impede the development of WBE. Here I describe how bottlenecks in the network can be non-obvious, and the merits of identifying them early. I show that bottlenecks may be predicted even with noisy forecasts. Accurate forecasts of WBE development must incorporate potential bottlenecks, which can be found using detailed descriptions of the WBE technology network. Bottlenecks identification can also increase the impact of WBE researchers by directing effort to those technologies that will immediately affect the timeline of WBE development

Eliminating Knowledge Bottlenecks Using Fuzzy Logic

Abstract

In the formation of new processes, innovations generated by people possessing the right knowledge and talent play a crucial role. Our starting point was the fact that every new change in processes can alter the knowledge structure of a work position or work role. This means that a person can become a knowledge bottleneck in the process. If this person is found on a critical path, the process cannot produce the output in a desired form, extent or quality, unless the bottleneck is removed. For this reason, we developed a decision model founded on fuzzy logic. The result of the fuzzy model is knowledge estimation based on deviation between the required and actual knowledge. For faster decision making, we made a presentation of allocated people on desired roles using the heat map technique. Therefore, the employers make better decisions on actual knowledge allocation, acquiring missing knowledge, or defining knowledge required for the future, which makes them more competitive.

Analysis of performance bottleneck of P2P grid applications

Abstract

The OurGrid distributed environment is an open source grid middleware that enables the creation of P2P computational grids to speed up the execution of bag-of-tasks applications. Bag-of-tasks is an application model composed of several independent tasks not communicating with each other during their execution, tolerating network delays and faults. The paper shows that the main advantage to avoid bottlenecks is if the data gets larger or computations become more complex and the conclusion is made based on the presented measurements. Understanding such patterns sheds an insightful light on performance bottlenecks and design tradeoffs for P2P Grid applications

The influence of knowledge management “bottleneck” on company’s performance

Abstract

Interviews with 10 marketing managers of 10 four-wheeled motor vehicle brand in Jakarta that have the highest sales in January up to April 2017 show that the managers do not have enough cognitive understanding of knowledge management (KM). However, the managers, in general, are very eloquent when discussing about practical business aspects such as supply-chain, business competition, products, organizational culture, and company’s performance. Based on previous research, KM was placed as independent or intervening or moderating variable on company’s performance. The aim of this study is to analyze the role of KM on company’s performance. By using stratified random sampling, linear regression, moderated regression, and path analysis, it can be concluded that KM can be as independent, moderating, or intervening variable. KM becomes similar to a “bottleneck” when the managers do not know well what and how to implement KM. Therefore, this study suggests that needed further researches are needed to explore the role of KM and to understand how KM can be implemented in a company in order to sustainably improve the company’s performance.

Phosphorus as a Bottleneck for a Sustainable Food Suply

Summary

Phosphorus is an essential nutrient for all forms of life, which means that food cannot be produced without it. As the phosphate rock (concentrated source of phosphorus) is a non-renewable and finite resource, with no substitute, without more sustainable management of phosphorus its deposits could be depleted in a rather short period. In addition, much of phosphorus eventually ends up in environment, where it causes pollution. Hence, one could say that the lack of phosphorus and its inappropriate management could be a bottleneck for a sustainable food supply and agricultural development in general. Nevertheless, unlike some other challenges that modern agriculture has to face (for example, water and energy scarcity, climate changes etc) the problem of phosphorus limited availability and accessibility has been largely neglected until recently. This paper’s particular intention is to explain why phosphorus management is one of key issues for the sustainable food supply and agricultural development, which factors have to be considered when dealing with this topic and which technologies could be applied as potential solutions. One solution to become independent from the fossil deposits of phosphorus might be its extraction from wastewater, which could contribute significantly to overcome the looming phosphorus and growing environmental crisis.
