Implicit discount rates (IDRs) are employed in energy models to capture household investment decisions, yet the factors behind IDR and their respective implications for policy-making usually remain blurred fractional. The proposed comprehensive framework distinguishes three broad categories of underlying adoption energy-efficient technologies (EETs): preferences (notably over time, risk, loss, debt, environment), predictable (ir)rational behavior (bounded rationality, rational inattention,...
As datacenters continue to scale in size, energy efficiency for short reach (<; 2 km) links is a major factor networks that may connect hundreds of thousands servers. We demonstrate based on analog coherent detection (ACD) offer promising path simultaneously achieving significantly larger link budgets and improved efficiency. A complete analysis presented considers the power consumption all photonic electronic components necessary realize an ACD architecture 50 Gbaud (GBd) quadrature...
Abstract This paper empirically analyzes how individual characteristics are associated with risk aversion, loss time discounting, and present bias. To this end, we conduct a large-scale demographically representative survey across eight European countries. We elicit preferences using incentivized multiple price lists jointly estimate preference parameters to account for their structural dependencies. Our findings suggest that linked variety of such as age, gender, income well some personal...
Optical phased arrays (OPAs) with arrayed waveguide gratings (AWGs) enable two-dimensional (2D) beam steering through wavelength tuning. Achieving a high vertical resolution for practical applications remains challenging due to the phase errors associated large AWG required. Here, we present high-resolution 65-channel AWG-assisted OPA 5 inputs. Ultra-low loss silicon nitride technology and transverse magnetic mode operation are employed error mitigation. A of 0.3° using single input is...

Inkjet technology as a maskless, direct-writing offers the potential for structured deposition of functional materials realization electrodes for, e.g., sensing applications. In this work, were realized by inkjet-printing commercial nanoparticle gold ink on planar substrates and, first time, onto 2.5D surfaces 0.5 mm-deep microfluidic chamber produced in cyclic olefin copolymer (COC). The challenges poor wetting behavior and low process temperature COC used solved pretreatment with oxygen...
A Physical Unclonable Function uses random and inherent properties of a physical entity can be used to uniquely identify components e.g., for anti-counterfeiting purposes. In this work we demonstrate that the surface patterns injection moulded plastic themselves are inherently unique hence as PUF reliable secure identification. We further these easily accessible since they photographed with simple camera set-up. This is exemplarily demonstrated two different materials on an overall 200...
Timing premia measure how much consumption people are willing to forgo resolve all uncertainty immediately. We develop a novel experiment elicit these attitudes directly in model-free way. On average, subjects around 5% of their total Recursive utility models postulate structural link between timing and deep preference parameters. parameters separately estimate corresponding predicted premia. Comparing elicited allows us test this link. Surprisingly, we find negative correlation
In this work, a polymer microlens array (MLA) for hyperspectral imaging (HSI) system is produced by means of ultraprecision milling (UP-milling) and injection compression molding. Due to the large number over 12,000 microlenses on less than 2 cm², fabrication process challenging requires full control. The study evaluates chain optimizes single steps achieve high quality MLAs. Furthermore, design elements like mounting features are included facilitate integration into final HSI system. mold...
Abstract Experiments involving games have two dimensions of difficulty for subjects in the laboratory. One is understanding rules and structure game other forming beliefs about behavior players. Typically, these cannot be disentangled as belief formation crucially depends on game. We present one-player guessing game, a variation two-player (Grosskopf Nagel 2008), which turns an otherwise strategic into individual decision-making task. The results show that majority fail to understand...
Smith et al. (1988) reported large bubbles and crashes in experimental asset markets, a result that has been replicated many times. Here we test whether the occurrence of depends on subjects’ cognitive sophistication. In two-part experiment, first run battery tests to assess sophistication classify them into low or high levels. We then invite separately two market experiments populated only by subjects with either observe classic bubble crash patterns sessions levels Yet, no are observed our...

This paper presents a feasibility study of an automated pick-and-place process for ultrathin chips on standard automatic assembly machine. So far, scientific research about chips, with thicknesses less than 50 µm, is missing, but necessary cost-effective, high-quantity production system-in-foil applications in narrow spaces or flexible smart health systems applied biomedical applications. Novel tools chip handling were fabricated and detachment from thermal release foil was developed. On...
