Today, multiple manufacturers have products rated at 230°C poised for market release. The tantalum anode, tantalum pentoxide dielectric and manganese dioxide primary cathode material stand up well to these temperatures, although some optimization of the design and manufacturing process for these materials have been required.

Presentation on KEMET's Characterization of Transient Liquid Phase Sintering (TLPS) materials and their use in MLCCs. Presented on October 5, 2015, at the Material Science & Technology Conference in Columbus, OH by Dr John Bultitude.
KEMET has been manufacturing conductive polymer based surface mount tantalum capacitors (KO-CAP[registered trademark]) since 1999. Capabilities have been successfully introduced into the market, such as low equivalent series resistance (ESR) series for decoupling, high voltage series for DC-DC converters and power management, and high-energy series for enterprise solid state drives (SSD) applications.
A recent application trend of conductive polymer based tantalum capacitors requires high performance in harsh environments. One example is the application in the automotive industry which requires AEC-Q200 qualification. Amongst all of the AEC-Q200 requirements, the most challenging one for polymer tantalum capacitors with traditional technology is the highly accelerated test under 85 [degree]C / 85% relative humidity (RH) with DC bias up to rated voltage for 1000 hours.
Other industries such as telecommunication are also starting to request 85 [degree]C / 85% RH qualification. A possible reason is an extrapolation based on data from other components that any device passing the 85 °C / 85% RH condition for 1000 hours could have field use life for 5 to 10 years under the real-life environmental conditions.
In this paper, the basic construction and manufacturing process of polymer Ta capacitors is first described. The challenges for polymer Ta capacitors under unbiased and biased high temperature and high humidity conditions will be discussed. This will be followed by possible technical solutions and the performance of our current Polymer Electrolytic T598 series of products.
Abhijit Gurav presented the latest data we've collected on our BME Ceramic DC Link capacitor platform. These C0G ceramic capacitors are designed for high frequency and high-temperature DC Link applications. This update was presented at APEC 2017 in Tampa, FL.
As we see the switching frequency of power converters rise, there is a clear need for a high-frequency and high-temperature capacitor solution. Some designs are looking to place a relatively small ceramic capacitor right at the silicon. These requirements mean these capacitors must withstand temperatures as high as 200°C while responding to frequencies in the MHz range. KEMET's Ceramic DC Link capacitors are based on our very popular C0G platform.
Our Base Metal Electrode (BME) development provides designers two options. Capacitors based on the ultra-stable C0G dielectric or U2J dielectric. In this presentation, KEMET shows potential packages, capacitances, and rated voltages with these two technologies.
Capacitors are more than just a couple electrode plates separated by a dielectric. KEMET offers an interactive online tool to simulate capacitor performance with Voltage, Temperature, and Frequency. The tool is available at http://ksim.kemet.com/.
This presentation reviews some of K-SIM's capabilities and techniques for using it.
Experiences with MnO2 tantalum capacitors in the past may have caused some engineers to look at alternatives. However, a decade of a new Polymer tantalum solve many of the previous challenges, especially in Automotive applications.
KEMET's T598 Polymer Electrolytic Capacitor is an AEC-Q200 qualified solution for automotive.

KEMET Webinar - 0805 and 1206 footprints now available with higher rated volt...Markus Trautz
The "evergreen" application requirement for miniaturization has driven the development of small case size Polymer Capacitors to rated voltage levels of 25V now. In case sizes 0805 (4.7µF/25V) and 1206 (="A Case" footprint with max. height of 1.2 mm, 10µF/25V) customers can now benefit from the stable capacitance with DC voltage applied as well as the usage for application voltages up to 22.5V in case sizes usually known from Multi-Layer Ceramic Capacitors (MLCC´s).
With the MLCC technology undergoing changes towards even smaller case sizes and facing extended lead times, small case size Polymer Capacitors can represent an interesting alternative for your Capacitance requirement.

Copper alloy conductors for overhead lines - CIGRÉ Regional South-East Europe...Leonardo ENERGY
Transmission network operators are facing substantial and often contradictory challenges. A highly variable renewable energy supply and an increased focus on energy efficiency require the reinforcement of the grid. However, resistance to the construction of new lines is huge. Micro-alloyed copper conductors can be part of the solution. Their energy efficiency and their ability to cope with temporary capacity overloads are highly valued features. Such overloads are possible due to the higher resistance of copper against creep at high temperatures. The energy efficiency of the copper conductor compensates for its higher initial cost. As a result, its life cycle cost (LCC) is often lower than that of a steel reinforced aluminium (ACSR) conductor. This was the finding of two feasibility studies conducted by DNV GL (KEMA). The first study examined the construction of new lines; the second investigated the refurbishment of existing lines. The latter study also demonstrated why the higher specific weight of copper compared to an ACSR conductor does not require any reinforcement of the overhead line towers. The smaller cross section combined with a hydrophobic coating results in a much lower wind and ice load, which is a decisive factor for determining the required strength of the towers. This makes the copper conductor particularly suitable in cold and windy climates.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
