Um Prozessschritte und damit wertvolle Zeit zu sparen, sollen die Kupferdickdrähte für die Leistungshalbleiter auch für die Kontaktierung von eingespritzten Anschlusssteckern im Modulrahmen verwendet werden. Das Kontaktierungsverfahren mit diesen Drähten auf Steckern in dünnwandigen Kunststoffrahmen führt häufig zu unzureichender Bondqualität. In dieser Arbeit wird das Bonden von Anschlusssteckern experimentell und anhand von Simulationen untersucht, um die Prozessstabilität zu steigern.\r\n\r\nZunächst wurden Experimente auf Untergründen mit hoher Steifigkeit durchgeführt, um Störgrößen von Untergrundeigenschaften zu verringern. Die gewonnenen Erkenntnisse erlaubten die Entwicklung eines Simulationsmodells für die Vorhersage der Bondqualität. Dieses basiert auf einer flächenaufgelösten Reibarbeitsbestimmung im Fügebereich unter Berücksichtigung des Ultraschallerweichungseffektes und der hierdurch entstehenden hohen Drahtverformung.\r\n\r\nExperimente an den Anschlusssteckern im Modulrahmen zeigten eine verringerte Relativverschiebung zwischen Draht und Stecker, was zu einer deutlichen Verringerung der Reibarbeit führt. Außerdem wurden verminderte Schwingamplituden des Bondwerkzeugs nachgewiesen. Dies führt zu einer weiteren Reduktion der Reibarbeit. Beide Effekte wurden mithilfe eines Mehrmassenschwingers modelliert. Die gewonnenen Erkenntnisse und die erstellten Simulationsmodelle ermöglichen die Entwicklung von Klemmvorrichtungen, welche die identifizierten Störgrößen gezielt kompensieren und so ein verlässliches Bonden der Anschlussstecker im gleichen Prozessschritt ermöglichen, in dem auch die Leistungshalbleiter kontaktiert werden."}],"extern":"1","date_created":"2023-02-10T13:05:19Z","status":"public","volume":15,"keyword":["heavy copper bonding","wire bonding","quality prediction","friction model","point-contact-element"],"author":[{"last_name":"Althoff","full_name":"Althoff, Simon","first_name":"Simon"}],"publisher":"Shaker","intvolume":" 15","_id":"41971","supervisor":[{"last_name":"Sextro","id":"21220","first_name":"Walter","full_name":"Sextro, Walter"}],"page":"192","year":"2023","type":"dissertation","citation":{"ieee":"S.

The model is relevant in markets such as public health care, education and schooling, or postal services. We find that, when the regulated price is low or intermediate, the entrant strategically locates towards the corner of the market to keep the incumbent at the low monopoly quality level. For a high price, the entrant locates at the corner of the market and both providers implement higher quality compared to a monopoly. In any case, the entrant implements higher quality than the incumbent provider. Social welfare is always higher in a duopoly if the cost of quality is low. For higher cost levels welfare is non-monotonic in the price and it can be optimal to the regulator not to use its entire budget. Therefore, the welfare effect of entry depends on the price and the size of the entry cost, and the regulator should condition the decision to allow entry on an assessment of the entry cost.","lang":"eng"}],"user_id":"37339","title":"Price Regulation, Quality Competition and Location Choice with Costly Relocation","author":[{"id":"37339","last_name":"Hehenkamp","full_name":"Hehenkamp, Burkhard","first_name":"Burkhard"},{"last_name":"Kaarbøe","full_name":"Kaarbøe, Oddvar M.","first_name":"Oddvar M."}],"keyword":["Quality competition","Price regulation","Location choice","Product differentiation"],"department":[{"_id":"280"},{"_id":"475"}],"status":"public","project":[{"_id":"1","name":"SFB 901: SFB 901"},{"_id":"2","name":"SFB 901 - A: SFB 901 - Project Area A"},{"_id":"7","name":"SFB 901 - A3: SFB 901 - Subproject A3"}],"date_created":"2023-04-20T17:12:18Z","jel":["D43","L13","L51"],"publication_status":"submitted","date_updated":"2023-04-20T17:16:24Z","_id":"44093","language":[{"iso":"eng"}],"year":"2023","type":"report","citation":{"ieee":"B.

They also provide promising advantages over traditional means of authentication, such as resistance to external observability, revocability, and intrinsic liveness detection. However, most of the research so far has been conducted with expensive, bulky, medical-grade helmets, which offer limited applicability for everyday usage. With the aim to bring brainwave authentication and its benefits closer to real world deployment, we investigate brain biometrics with consumer devices. We conduct a comprehensive measurement experiment and user study that compare five authentication tasks on a user sample up to 10 times larger than those from previous studies, introducing three novel techniques based on cognitive semantic processing. Furthermore, we apply our analysis on high-quality open brainwave data obtained with a medical-grade headset, to assess the differences. We investigate both the performance, security, and usability of the different options and use this evidence to elicit design and research recommendations. Our results show that it is possible to achieve Equal Error Rates as low as 7.2% (a reduction between 68–72% with respect to existing approaches) based on brain responses to images with current inexpensive technology. We show that the common practice of testing authentication systems only with known attacker data is unrealistic and may lead to overly optimistic evaluations. With regard to adoption, users call for simpler devices, faster authentication, and better privacy.\r\n "}],"status":"public","date_created":"2023-10-14T12:11:55Z","volume":26,"publisher":"Association for Computing Machinery (ACM)","author":[{"last_name":"Arias-Cabarcos","full_name":"Arias-Cabarcos, Patricia","first_name":"Patricia"},{"last_name":"Fallahi","full_name":"Fallahi, Matin","first_name":"Matin"},{"last_name":"Habrich","full_name":"Habrich, Thilo","first_name":"Thilo"},{"last_name":"Schulze","first_name":"Karen","full_name":"Schulze, Karen"},{"last_name":"Becker","first_name":"Christian","full_name":"Becker, Christian"},{"first_name":"Thorsten","full_name":"Strufe, Thorsten","last_name":"Strufe"}],"keyword":["Safety","Risk","Reliability and Quality","General Computer Science"],"publication":"ACM Transactions on Privacy and Security","issue":"3","_id":"48063","intvolume":" 26","type":"journal_article","citation":{"short":"P.

Here k is a granularity parameter 1 {$\\leq$} k {$\\leq$} n+1. We give a tight bound on the expected time until all cells are covered for arbitrary fitness functions and for all k and analyse the expected optimisation time of QD on OneMax and other problems whose structure aligns favourably with the feature space. On combinatorial problems we show that QD finds a (1 - 1/e)-approximation when maximising any monotone sub-modular function with a single uniform cardinality constraint efficiently.

However, vulnerabilities in the executed program give attackers ample opportunities to execute arbitrary code inside the enclave. This code can modify the dataflow of the program and leak secrets via SGX side channels. Fully homomorphic encryption would be an alternative to compute on encrypted data without data leaks. However, due to its high computational complexity, its applicability to general-purpose computing remains limited. Researchers have made several proposals for transforming programs to perform encrypted computations on less powerful encryption schemes. Yet current approaches do not support programs making control-flow decisions based on encrypted data.\r\n \r\n We introduce the concept of\r\n dataflow authentication\r\n (DFAuth) to enable such programs. DFAuth prevents an adversary from arbitrarily deviating from the dataflow of a program. Our technique hence offers protections against the side-channel attacks described previously. We implemented two flavors of DFAuth, a Java bytecode-to-bytecode compiler, and an SGX enclave running a small and program-independent trusted code base. We applied DFAuth to a neural network performing machine learning on sensitive medical data and a smart charging scheduler for electric vehicles. Our transformation yields a neural network with encrypted weights, which can be evaluated on encrypted inputs in\r\n \r\n \\( 12.55 \\,\\mathrm{m}\\mathrm{s} \\)\r\n \r\n . Our protected scheduler is capable of updating the encrypted charging plan in approximately 1.06 seconds.\r\n "}],"user_id":"15249","year":"2022","citation":{"short":"A. Fischer, B. Fuhry, J.

However, an increase in model accuracy with state-of-the-art methods, such as deep convolutional neural networks, results in less interpretability and transparency. Due to the ease of implementation, interpretation and transparency to both domain experts and non-experts, a rule-based method is proposed in this paper, for prognostics and health management (PHM) and specifically for diagnostics. The proposed method utilizes the most relevant sensor signals acquired via feature extraction and selection techniques and expert knowledge. As a case study, the presented method is evaluated on data from a real-world quality control set-up provided by the European prognostics and health management society (PHME) at the conference’s 2021 data challenge.

We found that: (1) Attention to SET originated in the US in the 1970s, spreading to German-speaking countries in the mid-1990s and continuing in China and Latin America in the early 2000s. (2) SET is commonly viewed as a control tool deserving methodological improvement, while bias is debated in the US. We also found local trajectories: (3) Whereas in the US and Latin America SET is primarily seen as a management tool, German-speaking and Chinese authors reflect more on improving teaching. Chinese scholars consider SET a valid instrument for state control associated with artificial intelligence. Also, (4) SET is commonly used in medical education in the US and the German-speaking region and in physical education in China. We conclude that SET is discussed cross-nationally but affected by national path dependencies.","lang":"eng"}],"article_type":"original","extern":"1","user_id":"90339"},{"department":[{"_id":"427"}],"publication_identifier":{"issn":["0192-513X","1552-5481"]},"publication_status":"published","title":"Intergenerational Value Similarity in Adulthood","language":[{"iso":"eng"}],"date_updated":"2022-08-29T06:34:26Z","oa":"1","doi":"10.1177/0192513x20943914","author":[{"full_name":"Hoellger, Christian","first_name":"Christian","last_name":"Hoellger"},{"first_name":"Sabrina","full_name":"Sommer, Sabrina","last_name":"Sommer"},{"first_name":"Isabelle","full_name":"Albert, Isabelle","last_name":"Albert"},{"id":"27152","last_name":"Buhl","full_name":"Buhl, Heike M.","first_name":"Heike M."}],"publisher":"SAGE Publications","publication":"Journal of Family Issues","keyword":["Adult child–parent dyads","value similarity","relationship quality","frequency of contact","parent-child-relationship"],"status":"public","date_created":"2022-08-03T05:56:45Z","volume":42,"abstract":[{"lang":"eng","text":"This investigation concentrates on value similarity between parents and their children during adulthood.

Regarding relationship quality, verbal intimacy was not related to value similarity. Parental satisfaction was associated with value similarity in the father–child dyads.

Asymmetries between intermediaries may arise due to distinct product qualities as well as by reasons of different production technologies. The intermediaries compete on the output market by choosing production quantities sequentially and for the supplies of a monopolistic input supplier on the input market. It turns out that there exist differences in product quality and productivities such that an intermediary being the Stackelberg leader has no incentive to procure inputs, whereas in the role of the Stackelberg follower will participate in the market. Moreover, we find that given an intermediary is more competitive, his equilibrium output quantity is higher when being the leader than when being the follower. Interestingly, if the intermediary is less competitive and goods are complements, there may exist asymmetries such that an intermediary being in the position of the Stackelberg follower offers higher output quantities in equilibrium than when being in the position of the Stackelberg leader."}],"type":"working_paper","citation":{"short":"J.

We also find that mandatory IFRS adopters pay lower bond yield spreads, but not lower loan spreads, after the mandate. These findings are consistent with debt providers responding positively to financial reporting of higher quality and comparability, but only when there is a greater reliance on publicly available financial statements than private communication. Lastly, we document that the observed debt market benefits are concentrated in countries with larger differences between domestic GAAP and IFRS and are present even for EU countries that did not experience concurrent financial reporting enforcement or other institutional reforms.

To achieve the same process stability when using copper wire instead of aluminum wire a profound understanding of the bonding process is needed. Due to the higher hardness of copper compared to aluminum wire it is more difficult to approach the surfaces of wire and substrate to a level where van der Waals forces are able to arise between atoms. Also, enough friction energy referred to the total contact area has to be generated to activate the surfaces. Therefore, a friction model is used to simulate the joining process. This model calculates the resulting energy of partial areas in the contact surface and provides information about the adhesion process of each area. The focus here is on the arising of micro joints in the contact area depending on the location in the contact and time. To validate the model, different touchdown forces are used to vary the initial contact areas of wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built up to identify the known phases of pre-deforming, cleaning, adhering and diffusing for the real bonding process to map with the model. Test substrates as DBC and copper plate are used to show the different formations of a wedge bond connection due to hardness and reaction propensity. The experiments were done by using 500 $\\mu$m copper wire and a standard V-groove tool."}]},{"user_id":"55222","abstract":[{"text":"(K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric materials with high piezoelectric properties.
