Demand Forecasts

From the on-line point, we consider the hospital’s medical examination appointment problem with hierarchical machines. This approach eliminates the need for both demand forecasts and a risk-neutrality assumption. Due to different unit revenue, uncertain demand, and arrival of patients, we design on-line booking policies for two kinds of different situations from the perspective of on-line policy and competitive analysis. After that, we prove the optimal competitive ratios. Through numerical examples, we compare advantages and disadvantages between on-line policies and traditional policies, finding that there is different superiority for these two policies under different arrival sequences.

Multiple Units

The emergence of auction that supports bids characterized by several attributes is one of the most recent evolutions within auction theory. The purpose of this paper is to introduce multi-attribute into the on-line auction mechanism, proposed by Lavi and Nisan. Our mechanism is designed for auctioning multiple units of a good when the bidders arrive and depart dynamically. To incorporate the buyer’s preferences across attributes in an auction setting, we adopt a novel application of a scoring function. Furthermore, we describe a competitive reservation utility strategy (RUS), which helps the buyer decide when and how many goods he should buy. Finally, we also perform numerical examples showing our results.

Abstract Gas chromatography (GC) is an important and widely used technique for separation and analysis in the field of analytical chemistry. Micro gas chromatography has been developed in response to the requirement for on-line analysis and on-site analysis. At the core of micro gas chromatography, microelectromechanical systems (MEMs) have the advantages of small size and low power consumption. This article introduces the stationary phases of micro columns in recent years, including polymer, carbon materials, silica, gold nanoparticles, inorganic adsorbents and ionic liquids. Preparation techniques ranging from classical coating to unusual sputtering of stationary phases are reviewed. The advantages and disadvantages of different preparation methods are analyzed. The paper introduces the separation characteristics and application progress of MEMs columns and discusses possible developments.

Automated Sampling

Timely monitoring and control of critical process parameters and product attributes are still the basic tasks in bioprocess development. The current trend of automation and digitization in bioprocess technology targets an improvement of these tasks by reducing human error and increasing through-put. The gaps in such automation procedures are still the sampling procedure, sample preparation, sample transfer to analyzers, and the alignment of process and sample data. In this study, an automated sampling system and the respective data management software were evaluated for system performance; applicability with HPLC for measurement of vitamins, product and amino acids; and applicability with a biochemical analyzer. The focus was especially directed towards the adaptation and assessment of an appropriate amino acid method, as these substances are critical in cell culture processes. Application of automated sampling in a CHO fed-batch revealed its potential with regard to data evaluation. The higher sampling frequency compared to manual sampling increases the generated information content, which allows easier interpretation of the metabolism, extraction of e.g., ks values, application of smoothing algorithms, and more accurate detection of process events. A comparison with sensor technology shows the advantages and disadvantages in terms of measurement errors and measurement frequency.

Deterministic Strategy

We introduce the compound interest rate into the continuous version of the online leasing problem and discuss the generalized model by competitive analysis. On the one hand, the optimal deterministic strategy and its competitive ratio are obtained; on the other hand, a nearly optimal randomized strategy is constructed and a lower bound for the randomized competitive ratios is proved by Yao's principle. With the help of numerical examples, the theoretical results show that the interest rate puts off the purchase date and diminishes the uncertainty involved in the decision making.

After the advantages and disadvantages of current methods of calibration are analyzed and contrasted, the comparatively widely applied Zhang Zhengyou calibration method is adopted in this paper, but it is used to solve problems in a different way. The calibration of a double-priority camera on the basis of a round planar target is proposed, and a computation method based on the on-line intersection of the two circles with the closest proximity is put forward to fix the center of a circle. This method of calibration is simple and flexible, with good robustness, precision, and practical value.

"In Romania, schools were closed, courses were suspended on March 11, 2020. The Ministry of Education and Research sent teachers the recommendation to conduct online courses at home. Over the following weeks, this recommendation was supplemented by others, the Ministry recommend that teachers take online courses, without making them compulsory. On March 20, 2020, the Ministry of Education approved the Methodology on the distance continuation of the educational process in quarantine conditions that establishes the way to continue the educational process in primary, secondary and high school institutions in quarantine conditions. The methodology establishes the obligation to conduct distance learning courses through various online platforms (eg Viber, Whatsapp, Facebook, Google Classroom, Zoom, etc.) and allows the assessment of students during this period and the registration of grades in the catalog. The large number of platforms available online for conducting such courses, as well as the lack of a national or local decision on the use of a single platform, has generated quite a bit of confusion among teachers and especially among students. We wanted to find out the opinions of primary school teachers regarding the advantages and disadvantages they perceive regarding online teaching, through interviews with them."
