- BER estimation from measured EVM values is shown experimentally for QPSK and 16QAM optical signals with 28 GBd. Various impairments, such as gain imbalance, quadrature error and timing skew, are introduced into the transmitted signal in order to evaluate the robustness of the method. The EVM was measured using two different real-time sampling systems and the EVM measurement accuracy is discussed.

- Digitization of the manufacturing and assembly sector is important to set up Industry 4.0. In this process, one of the key factors is the channel of sharing and distributing information on the shop floor. This study highlights the implementation of digital work instructions in the manufacturing and assembly sectors and finds the benefits that it could bring to the industry. The study was conducted in a large production plant with over five hundred workers in Malaysia and was carried out for almost a year. Whereas, most of the existing studies have been conducted in a controlled environment with a group of inexperienced workers in manufacturing and assembly tasks. In this article, the benefits and challenges of digital work instructions are studied over paper-based textual representation of assembly instructions. The study was conducted among groups of people with different roles, such as electrical assembly, mechanical assembly, and final quality check. The qualitative analysis is carried out based on the survey conducted among operators with different roles. Results show that digitalization eases the work for the quality inspection group. In contrast, people with other tasks are either neutral or find it more difficult to work with digitalized versions over paper-based instructions. In addition to this, some data-driven facts are presented, which help in improving the plant operations. This includes recording material shortages, optimizing working hours, and having real-time updates on production status which leads to effective production planning. At last, with the collected information, manufacturing plants can also optimize power utilization that impacts the environment in a positive direction.

Selecting cases of major psychiatric and substance use disorders in Swedish national registries on the basis of clinical features to maximize the strength or specificity of the genetic risk
- 2023
-
Ingår i: Molecular Psychiatry. - 1359-4184. ; 28, s. 5195-5205

Tidskriftsartikel (refereegranskat)abstract
- We investigate how selection of psychiatric cases by phenotypic criteria can alter the strength and specificity of their genetic risk by examining samples from national Swedish registries for five disorders: major depression (MD, N = 158,557), drug use disorder (DUD, N = 69,841), bipolar disorder (BD, N = 13,530)) ADHD (N = 54,996) and schizophrenia (N = 11,227)). We maximized the family genetic risk score (FGRS) for each disorder and then the specificity of the FGRS in six disorder pairs by univariable and multivariable regression. We use split-half methods to divide our cases for each disorder into deciles for prediction of genetic risk magnitude and quintiles for prediction of specificity by FGRS differences between two disorders. We utilized seven predictor groups: demography/sex, # registrations, site of diagnosis, severity, comorbidity, treatment, and educational/social variables. The ratio of the FGRS in the upper vs two lower deciles from our multivariable prediction model was, in order, DUD – 12.6, MD – 4.9, BD – 4.5, ADHD – 3.3 and schizophrenia 1.4. From the lowest to highest quintile, our measures of genetic specificity increased more than five-fold for i) MD vs. Anxiety Disorders, ii) MD vs BD, iii) MD versus alcohol use disorder (AUD), iv) BD vs schizophrenia and v) DUD vs AUD. This increase was nearly two-fold for ADHD vs DUD. We conclude that the level of genetic liability for our psychiatric disorders could be substantially enriched by selection of cases with our predictors. Specificity of genetic risk could also be substantially impacted by these same predictors.

Using the Scharff-technique to elicit information: How to effectively establish the "illusion of knowing it all"?
- 2016

Tidskriftsartikel (refereegranskat)abstract
- The Scharff-technique is used for eliciting information from human sources. At the very core of the technique is the "illusion of knowing it all" tactic, which aims to inflate a source's perception of how much knowledge an interviewer holds about the event to be discussed. For the current study, we mapped the effects following two different ways of introducing this particular tactic; a traditional way of implementation where the interviewer explicitly states that s/he already knows most of the important information (the traditional condition), and a new way of implementation where the interviewer just starts to present the information that s/he holds (the just start condition). The two versions were compared in two separate experiments. In Experiment 1 (N = 60), we measured the participants' perceptions of the interviewer's knowledge, and in Experiment 2 (N = 60), the participants' perceptions of the interviewer's knowledge gaps. We found that participants in the just start condition (a) believed the interviewer had more knowledge (Experiment 1), and (b) searched less actively for gaps in the interviewer's knowledge (Experiment 2), compared to the traditional condition. We will discuss the current findings and how sources test and perceive the knowledge his or her interviewer possesses within a framework of social hypothesis testing.

Merging Directed C-H Activations with High-throughput Experimentation : Development of Predictable Iridium-catalyzed C-H Aminations Applicable to Late-stage Functionalizations
- 2022
-
Ingår i: JACS Au. - : American Chemical Society (ACS). - 2691-3704. ; 2:4, s. 906-916
-
Tidskriftsartikel (refereegranskat)abstract
- Herein, we report an iridium-catalyzed directed C–H amination methodology developed using a high-throughput experimentation (HTE)-based strategy, applicable for the needs of automated modern drug discovery. The informer library approach for investigating the accessible directing group chemical space, in combination with functional group tolerance screening and substrate scope investigations, allowed for the generation of reaction application guidelines to aid future users. Applicability to late-stage functionalization of complex drugs and natural products, in combination with multiple deprotection protocols leading to the desirable aniline matched pairs, serve to demonstrate the utility of the method for drug discovery. Finally, reaction miniaturization to a nanomolar range highlights the opportunities for more sustainable screening with decreased material consumption.

E2-RTO: An Exploitation-Exploration Approach for Real Time Optimization
- 2023
-
Ingår i: <em>IFAC-PapersOnLine</em>, 22nd IFAC World Congress. - : Elsevier BV. ; , s. 1423-1430

Konferensbidrag (refereegranskat)abstract
- In Real-Time Optimization, the problem of optimizing the operating conditions of a plant is solved through iterative methods that directly use plant measurements. In this paper, a novel Exploitation-Exploration approach to solve this problem is proposed. Differently from a previously proposed Two-Step approach, consisting in strict exploitation and consecutive model update, in the Exploitation-Exploration approach an additional exploration step is included, in which an exploration input is constructed so that the updated model would approximately minimize the expectation of the objective function value for the new exploitation step. The proposed algorithm is described and its validity is shown through a numerical example, where it is compared to some common Real-Time Optimization schemes.
