Intelligent Electric Power Management Using Zigbee with Advanced Metering Inf...Akbar Badusha
This project mainly focuses on reduction of power cut and power theft. The main reason for the power cut is shortage of power in the generation unit. We can rectify this problem through our project.
Whenever the generation falls behind a particular limit (it is set initially by EB) the power management system will automatically switched on. Power will be supplied to only the basic necessary equipment (as stated in the priority list) power to other load will be stopped so that huge amount of power can be saved without power cut.
In our project, this is achieved using NS2 software and using ZIGBEE. Whenever generation falls below the particular value, then the load will be automatically switched off based on priority. And it can also be done through an interrupt. Through ZIGBEE command the interrupt will be sent to microcontroller to cut the power to the particular load.
When microcontroller receiving the command, the relay will cut the power to the equipment. So the power will be saved.
In this project,the method to detect and to control the power theft is also stated. Other methods of power theft like damaging, by passing electrical power meter can also be detected and can be punished.
Man power can also be reduced. The power usage of the customer will be automatically updated in the EB station so there is no need of man power to take meter reading in the user side. After every two months the reading will be automatically resetted.

Simulation Analysis of Ac/Dc Adapter Under Zero No-Load Power Consumption usi...IJPEDS-IAES
The burst-mode control is generally used to regulate the output voltage of the ac/dc adapter under light or no-load condition. Although the burst-mode control reduces the switching loss, the control-IC and the feedback circuit at the output side still consume a large amount of power. In order to further reduce the power consumption at no-load condition, a zero no-load power (ZNP) ac/dc adapter for electronic equipment with an embedded battery is proposed in this paper. When the proposed adapter is load connected, the operation is same as that of the conventional adapter. At no-load condition, the adapter is totally turned off. As a result the adapter can reduce the no- load power consumption to less than 1mW. Simulation of a 65 W adapter is presented in order to verify its validity

PBZ Series Intelligent Bi-Polar Power Supplies
The PBZ series is a bipolar type DC regulated power source that can continuously change both + and – polarities passing through 0 without changing the output terminal.
By adopting a “Switching + Linear” system, the PBZ is able to realize both drastic weight reduction as well as high speed and low noise operation. Since operation covers 4 quadrants, power can be both supplied (source) and absorbed (sink). The PBZ can also drive inductive or capacitive loads. The unit also equips a signal generator function which enables waveform and sequence creation. The PBZ is also capable of synchronized operation which is required for voltage variation tests, and it can also be expanded for large current applications through master-slave parallel operation.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation.

Key Trends Shaping the Future of Infrastructure.pdfCheryl Hung
Keynote at DIGIT West Expo, Glasgow on 29 May 2024.

The key trends across hardware, cloud and open-source; exploring how these areas are likely to mature and develop over the short and long-term, and then considering how organisations can position themselves to adapt and thrive.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

For Evaluations of Next-Generation Communication Devices
Racing to develop large-capacity high-speed communication technology typified 5G has already begun shifting to a future communica-
tion infrastructure beyond 5G. However, there are a lot of issues to be faced such as expansion of wireless communication base stations,
development of optical fiber communication apparatus and development of higher-performance batteries necessary for mobile phones. To
realize such a high-speed communication, high-performance electronic devices and modules are essential. ADC offers you various types
of measuring instruments optimal for evaluating their basic performances.
…………… Applications
The limit reverse function is a function to make the output voltage in the
sweep measurement return to the start voltage when the current limit is
detected.
The limit reverse (multi slope) function is a function to vary the step volt-
age (Vstep) as shown below by comparing the measurement current (IM)
and the limit detection current (IL) at every step. Accordingly, the step
voltage can be finely changed around the current limit detection point.
Evaluation of Receiver Modules with Avalanche Photodiodes
The I-V characteristics of 4-channel receiver optical subassemblies (ROSA) with
avalanche photodiodes (APD) can be evaluated by using the 4000 and two units
of the 40052. The 40052 can perform VSIM (voltage source current measurement)
only with the input TRIAX cable by connecting the output terminal to the GND by
the “HIG1” command.
As the voltage source circuit of the 40052 adopts the same system as our SMUs,
no overshoot occurs and no stress is given to
devices because of the high-speed response
constant current system current limiter.
When there is a current limit of 100 µA with the
voltage source between 0 V and 200 V, dark
current characteristic measurement between
10 fA to 100 µA is available.
Voltage source: 0 to ±200 V
(minimum resolution: 1 mV)
Current measurement: 0 to ±3.2 mA
(minimum resolution: 10 fA)
Current limit: 10 µA to 3.2 mA
RF Front End Module Evaluation
The 6540 and 6541 are 4-channel compact DC Voltage Current Source/
Monitors having a low-noise feature (10 V range: 5 mVp-p).
As synchronous source and measurement across the channels are
available, the 6540 and 6541 are capable of low-noise voltage source,
signal application and current measurement with the minimum resolu-
tion of 10 pA by a single unit, and are suitable for evaluation of RF front
end modules that require controlling multiple terminals at the same
time.
GaN HEMT Breakdown Characteristic Measurement
Using the limit reverse (multi slope) function of the sweep measurement
in the sequence program No 6 of the 5450/5451 will allow you to mea-
sure the breakdown characteristics of GaN HEMTs.
(Maximum power per channel: ±10 V / ±500 mA, ±1 A for 4 channels)
Low-noise voltage can
be applied to 4 terminals
simultaneously.

Current Consumption Measurement of Digital Devices

–Variable Integration Time–
Mobile phones in the standby state and IOT sensors make communication
at a constant period and operate by momentary pulse current. Thus, to get
the current consumption, the average value measurement is essential.
The DC voltage current source monitors 6540, 6541 and 6253, the digital
multimeters 7451A, 7461A and 7461P, and the digital electrometer 5350
contain variable integration system-adopted A-D converters, so that they
can perform precise average current measurement by adjusting the inte-
gration time to the pulse period.

Mobile Phone Battery Evaluation
Our DC voltage current source monitors are capable of charge/dis-
charge test by bipolar output by a single unit. In current sink operation,
battery capacity evaluation is available. As for pulse discharge, the mini-
mum pulse width of 25 ms and the setting resolution of 1ms can be set,
allowing the evaluation of mobile phone batteries (6253).
Highly Stable Measurement of Sensor Output
The high-accuracy digital multimeter 7461A with 6½-digit display reso-
lution is suitable for inspections or quality control of various precision
sensors. When a highly stable power supply is required such as for load
cells, the DC voltage current source 6146 is applicable.
Electronic components and circuits used in CO2 reduction equipment must be controlled precisely. Typical examples are, high-efficiency DC/DC
converters and high-performance batteries. Our DC voltage/current source monitors and digital multimeters offer you optimal evaluation meth-
ods with unique functions and excellent performances.

DC/DC Converter Evaluation
The DC/DC converter evaluation is available by using two units of SMUs.
One SMU on the input side is set to the VSIM fixed sweep mode. The other
SMU on the output side is set to the ISVM linear sweep mode with negative
current. Then the input and output characteristics are measured by increasing
the load current.
The SYNC OUT signal from the SMU on the output side is connected to the
TRIGGER IN input of the SMU on the input side to perform synchronous mea-
surement.
The conversion efficiency is obtained by using the input power on the input
side Vi*Ii and the load power on the output side Io*Vo as follows: η=Io*Vo/(Vi*Ii)
The hysteresis characteristic can be also evaluated by setting the linear sweep
to the reverse mode.
DC/DC Converter Evaluation
Five types of measurements: input voltage/current on Ach, output volt-
age/current on Bch and temperature on rear TEMP are available using
the 7352A/7352E.
The input and output characteristics, load regulation, conversion effi-
ciency, and rise in temperature of a DC/DC converter can be evaluated
by a single unit.

For Test and Evaluations of Electronic Materials Used in Energy Saving Equipment
Insulation Material Volume/Surface Resistivity Measurement
Liquid Sample Volume Resistivity Measurement
The volume resistivity of liquid can be measured by using the digital
electrometer and the resistivity chamber for liquid sample 12707.
This accessory requires only 0.8 cc of sample for measurement.
Conductive Plastic and Connector
Low Resistance Measurement
The 6241A/6242/6240B can measure the contact resistance of con-
ductive plastics or connectors easily with a resolution of open-circuit
voltage 10 μV as shown below.
Especially the 6240B produces high-precision results by itself because
the thermal electromotive force (Vd) generated on the contact section
that may cause an error in low-resistance measurement can be can-
celed by switching the polarity of measurement current.
CO2 reduction materials have various characteristics. Fully measuring these characteristic leads to stable development of products. To
conduct insulation test or static electricity test of various materials including sheet, liquid, block and power, ADC offers high-performance
digital electrometers and sample boxes that fit various samples.
According to JIS K6911”Testing Methods for Thermosetting Plastics,”
the digital electrometer can measure the volume or surface resistivity
of sheet insulation materials in combination with the resistivity chamber
15042, 12704A or 12702A/B. Especially the 5450/5451 can perform mea-
surement while controlling the discharge, charge or measurement time
by using the sequence program.

For Tests and Evaluations of LEDs or Other Diodes and Semiconductor Devices
Diode Temperature Dependence Evaluation
The I-V characteristics of power diodes are difficult to measure cor-
rectly because of self-heating effect.
To avoid this, the DC voltage current source monitors measure effec-
tively the characteristics applying pulse current.
By using the current pulse sweep function and voltage measurement
in synchronous with pulses, precise VF characteristic test with large
current is available.
Temperature Dependence Device I-V Measurement
Some devices such as thermistor, posistor and PolySwitch generate
heat by receiving current. The DC voltage current sources can measure
not only the IV characteristic of these devices but also their temperature
dependence by generating constant current and measuring the device
resistance change with time.
The measured data is graphed on Excel by using the software down-
loaded from ADC’s website.
Diode Leak Current Measurement
The DC voltage current source monitors are capable of ISVM (current
source voltage measurement) and VSIM (voltage source current mea-
surement).
Diode I-V characteristics are measured by ISVM. In addition, micro
leak current can be measured by applying reverse voltage to diodes by
VSIM.
There are various types of semiconductor devices. Particularly, LED lights receive much attention as CO2 reduction devices because of
their power saving and long life characteristics.
Our DC voltage current source monitors have been developed from years of semiconductor test experiences, and have functions and per-
formance to evaluate their characteristics precisely and easily. In addition, free automatic measurement software can be downloaded from
our website.

Measurement Example of Light Source Stability
Using the interferometer method, the 8471 achieves a
maximum resolution of 0.001 nm (1 pm). Moreover, a high
measurement resolution of 0.0001 nm (0.1 pm) is possible by
performing average measurement of ten times or more.
The use of a He-Ne laser as reference wavelength enables
a high measurement accuracy of 2 ppm. The He-Ne laser
provides oscillation with a highly stable wavelength, assur-
ing high accuracy over a long term without calibration.
