Water Quality Monitoring System Using LoRaWAN
For effective process monitoring and enhanced control in wide areas, reliable and accurate real-time measuring is essential. LoRa, a low-power, wide-area network modulation technology (LPWAN), refers to long-range data communications. LoRa allows for long-range communications of up to three miles or five kilometers in urban areas and up to ten miles or 15 km in rural areas. The ultra-low power requirements of LoRa-based systems are a crucial feature, allowing for the design of battery-operated devices that can last up to 10 years. A star network based on the open LoRaWAN protocol is suitable for an implementation scheme that needs long-range or deep in-building communication.

IBM Db2 Family
Db2 is a family of data management products, including database servers, developed by IBM. They initially supported the relational model, but were extended to support object–relational features and non-relational structures like JSON and XML. The brand name was originally styled as DB/2, then DB2 until 2017 and finally changed to its present form.

Sustainable Wireless Sensor Network Based Environmental Monitoring
Wireless sensor networks (WSN) are the base of the Internet of Things (IoT) that all together give rise to the smart city. These WSNs consist of several sensors, which are densely distributed to observe physical or environmental conditions, like humidity, temperature, light intensity, and gas concertation. The sensors reading data are transmitted to the network coordinator, the IP-gateway, which is at the heart of the wireless network.

Minix 3
MINIX 3 is a small, Unix-like operating system. It is published under a BSD-3-Clause[lower-alpha 1] license and is a successor project to the earlier versions, MINIX 1 and 2. The project's main goal is for the system to be fault-tolerant by detecting and repairing its faults on the fly, with no user intervention. The main uses of the system are envisaged to be embedded systems and education. (As of 2017), MINIX 3 supports IA-32 and ARM architecture processors. It can also run on emulators or virtual machines, such as Bochs, VMware Workstation, Microsoft Virtual PC, Oracle VirtualBox, and QEMU. A port to PowerPC architecture is in development. The distribution comes on a live CD and does not support live USB installation. MINIX 3 is believed to have inspired the Intel Management Engine (ME) OS found in Intel's Platform Controller Hub, starting with the introduction of ME 11, which is used with Skylake and Kaby Lake processors. It was debated that MINIX could have been the most widely used OS on x86/AMD64 processors, with more installations than Microsoft Windows, Linux, or macOS, because of its use in the Intel ME. The project has been dormant since 2018, and the latest release is 3.4.0 rc6 from 2017, although the MINIX 3 discussion group is still active.

Twister
Twister is an experimental peer-to-peer microblogging program. It is decentralized, meaning that no one is able to shut it down as there is no single point to attack. The system uses end-to-end encryption to safeguard communications. It is based on both BitTorrent and Bitcoin-like protocols and has been likened to a distributed version of Twitter.

Forensic Palynology
Forensic palynology is a subdiscipline of palynology (the study of pollen grains, spores, etc.), that aims to prove or disprove a relationship among objects, people, and places that may pertain to both criminal and civil cases. Pollen can reveal where a person or object has been, because regions of the world, countries, and even different parts of a single garden will have a distinctive pollen assemblage. Pollen evidence can also reveal the season in which a particular object picked up the pollen. Palynology is the study of palynomorphs - microscopic structures of both animal and plant origin that are resistant to decay. This includes spermatophyte pollen, as well as spores (fungi, bryophytes, and ferns), dinoflagellates, and various other organic microorganisms - both living and fossilized. There are a variety of ways in which the study of these microscopic, walled particles can be applied to criminal forensics. In areas such as New Zealand, where the demand for this field is high, forensic palynology has been used as evidence in many different case types that range anywhere from non-violent to extremely violent crimes. Pollen has been used to trace activity at mass graves in Bosnia, pinpoint the scene of a crime, and catch a burglar who brushed against a Hypericum bush during a crime. Because pollen has distinct morphology and is relatively indestructible, it is likely to adhere to a variety of surfaces often without notice and has even become a part of ongoing research into forensic bullet coatings.

MIDAS Technical Analysis
In finance, MIDAS (an acronym for Market Interpretation/Data Analysis System) is an approach to technical analysis initiated in 1995 by the physicist and technical analyst Paul Levine, PhD, and subsequently developed by Andrew Coles, PhD, and David Hawkins in a series of articles and the book MIDAS Technical Analysis: A VWAP Approach to Trading and Investing in Today's Markets. Latterly, several important contributions to the project, including new MIDAS curves and indicators, have been made by Bob English, many of them published in the book. Paul Levine's initial MIDAS work and the new MIDAS approaches developed in the book and other publications by Coles, Hawkins, and English have been taught at university level and are currently the subject of independent study intended for academic publication. The same MIDAS techniques have also been widely implemented as part of private trader and hedge fund strategies. The MIDAS curves and indicators developed by Levine, Coles, Hawkins, and English have also been commercially developed by an independent trading software company for the Ninja Trader trading platform, while individual curves and indicators have been officially coded by developers of a large number of trading platforms, including Metastock, TradeStation, and eSignal. The new MIDAS curves and indicators are in line with the accomplished MIDAS goal of developing an independent approach to financial market analysis with unique standalone indicators available for every type of market environment while also offering information not available from other technical analysis systems.

Deep Learning for Classification of Skin Cancer
One of the major health concerns for human society is skin cancer. When the pigments producing skin color turn carcinogenic, this disease gets contracted. A skin cancer diagnosis is a challenging process for dermatologists as many skin cancer pigments may appear similar in appearance. Hence, early detection of lesions (which form the base of skin cancer) is definitely critical and useful to completely cure the patients suffering from skin cancer. Significant progress has been made in developing automated tools for the diagnosis of skin cancer to assist dermatologists. The worldwide acceptance of artificial intelligence-supported tools has permitted usage of the enormous collection of images of lesions and benevolent sores approved by histopathology.

History and Implementations of ZFS
The history and implementations of ZFS covers the development of the ZFS file system. ZFS began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris - including ZFS - were published under an open source license as OpenSolaris for around 5 years from 2005, before being placed under a closed source license when Oracle Corporation acquired Sun in 2009/2010. During 2005 - 2010, the open source version of ZFS was ported to Linux, Mac OS X (continued as MacZFS) and FreeBSD. In 2010, the illumos project forked a recent version of OpenSolaris, to continue its development as an open source project, including ZFS. In 2013 the co-ordination of open source ZFS moved to an umbrella organization, OpenZFS, which allowed any person or organization that wished to use the open source version of ZFS, to collaborate in developing and maintaining a single common version of ZFS. illumos remains very closely involved with OpenZFS. As of 2018, there are two main implementations of ZFS, both quite similar: Oracle's implementation, which is closed source and part of Solaris, and OpenZFS, which is widely used to provide ZFS on many unix-like operating systems.
